What is 3a squared?
Oh, what a happy little question! When we see "3a squared," we simply need to multiply 3 by a and then square the result. So, 3a squared is the same as 3 times a times a, which simplifies to 3a^2. Just like painting a beautiful landscape, math can be a lovely adventure of discovery and creativity.
Is it possible to make an expression which is equivalent to twenty using only three three's and any math operation?
No. You need at least four.
How do you solve the system of equations 3x-2y -7?
To solve a system of equations like 3x-2y=-7, you typically need another equation to find a unique solution. If there is only one equation given, the system is underdetermined and has infinite solutions. However, if you have additional information or constraints, you can potentially narrow down the possible solutions. In this case, without another equation or constraint, the system is unsolvable as it is currently presented.
How do you factorise the quadratic equation 2y squared - 2y -24?
2y2 - 2y - 24 has the factors (2y + 6) and (y - 4) There is a formula, but I always use trial and error. The factors of the non-x element need to be such that they can be added to give the middle element. So when you get 24, then you need to be looking at 2,12 - 3,8 - 4,6 When both the second and third element are minus values then there is a plus and a minus in the factors.
Evaluate the expression 17P2?
To "evaluate" an expression, you need to know the value for the variables.
How do you factor 2x squared minus 1?
you cant really simpliffy that expression you need an equation so just write 'cannot simplify' or 'already in simplest form'
How would you solve x to the 3rd plus 5x squared minus 25 x minus 125 over x to the 3rd power minus 1 x squared minus 1x plus 1?
The question contains an expression, not an equation (nor inequality). An expression cannot be solved. Without the value of x, it cannot be evaluated. And, since the numerator and denominator have no common factor, it cannot be simplified. You need to consider what exactly it is that you want a resubmit a question that makes sense.
How would you show all work for 1 minus 2cos squared theta?
You could not.1 - 2cos2theta is an expression which cannot be solved nor evaluated without information about theta. If you need to show its equivalence to another expression then it is necessary to know what the other expression is.
B squared minus a squared equals?
To evaluate it you need to know both b and a. But it is possible to factorise it as follows: b2-a2 = (b-a)*(b+a)
What is x squared minus y squared?
-- The number that (x2-y2) represents depends on the values of 'x' and 'y', which you haven't seen fit to include. -- When (x2-y2) is factored, it can be represented as [ (x+y) times (x-y) ], which is often easier to evaluate, or integrate, or differentiate, than the original expression is. But you still need to know the values of 'x' and 'y'.
What is negative x cubed minus negative x?
When simplifying the expression "-x^3 - (-x)", we first need to distribute the negative sign within the parentheses. This results in "-x^3 + x". Since subtracting a negative is equivalent to adding a positive, the expression simplifies further to "-x^3 + x". This is the final simplified form of the given expression.
Factor x squared minus y squared?
( x - y )2There isn't enough information to answer this question because they have two squared variables and you do not know what is being squared. You would first need to either know the value of one of the variables and an equation of the value of both of the variables before you would be able to factor.
N2 minus 11n minus 26 need to writte the expression in factored form?
n2 - 11n - 26what two factors of - 26 add up to - 11?(n + 2)(n - 13)===========
What is 4 times x squared?
The expression "4 times x squared" can be written as 4x^2, where x is a variable representing an unknown value. This expression represents four times the square of the variable x. To simplify this expression, you would multiply 4 by x squared, resulting in 4 times x squared.
Is x squared minus 5 prime?
X squared minus 5 is not necessarily prime. For instance; if x=3, then x squared minus 5 is 4, and 4 is not prime. Please consider this addition to the above answer. I opted to keep the original answer there for a reason... Whether x^2-5 is prime depends not on the values of x that you plug into the expression, but rather on the primality of the expression itself. In other words, the expression's primality (primeness) is based on the presence or absence of RATIONAL ROOTS. x^2-5 can be factored into (x+√5)(x-√5), making x=±√5. √5 is IRRATIONAL, and since no root of the original expression is rational, the original expression is PRIME. It is ALWAYS PRIME. For the sake of improved clarity, consider the following examples: x^2-4 is NOT PRIME because it can be represented by (x+2)(x-2), making x=±2, both of which are RATIONAL ROOTS. x^2-3 is PRIME because it can be represented by (x+√3)(x-√3), making x=±3, both of which are IRRATIONAL. I hope this helps! Please ask for clarification if you need it, as well as for any other form of assistance... including other questions.
How do you solve x squared -28?
There's nothing to solve. If it equaled something, you could solve it. For example, if x^2 - 28 = 0, then x = the square root of 28, which simplifies to plus or minus 2 times the square root of 7.
Why do my two different calculators both show minus three squared as negative nine instead of positive?
The minus (unary) operator is of lower precedence than the exponent. To force the square of a negative on some calculators you may need to surround the number in parentheses. E.g.
