4x2 - 12x + 9 = 4x2 - 6x - 6x + 9 = 2x(2x - 3) - 3(2x - 3)
= (2x - 3)(2x - 3) or (2x - 3)2
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.
No. You need at least four.
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.
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.
To "evaluate" an expression, you need to know the value for the variables.
you cant really simpliffy that expression you need an equation so just write 'cannot simplify' or 'already in simplest form'
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.
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.
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)
To determine which polynomial is equivalent to a given expression, you'll need to provide the specific expression you're referring to. Please share the expression, and I'll help you find the equivalent polynomial.
To simplify the expression "4x minus 6 22," we first need to clarify the expression. If it means (4x - 6 - 22), then we combine the constants to get (4x - 28). If the expression is intended differently, please provide clarification for an accurate answer.
-- 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'.
To factor the quadratic expression (x^2 + 7x - 8), we need to find two numbers that multiply to (-8) (the constant term) and add to (7) (the coefficient of the linear term). The numbers (8) and (-1) satisfy these conditions. Thus, we can factor the expression as ((x + 8)(x - 1)).
To achieve the result of 135 from the expression "seven squared plus one minus five times 3," you can place parentheses as follows: ( (7^2 + 1) - (5 \times 3) ). This simplifies to ( (49 + 1) - 15 ), which equals ( 50 - 15 = 35 ). However, to get 135, you could rephrase the expression as ( 7^2 + (1 - 5) \times 3 ), which evaluates to ( 49 + (-4) \times 3 = 49 - 12 = 37 ), still not yielding 135. Thus, the expression may need reevaluation or a different arrangement to meet the requirement.
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.
To find the value of the expression ( a^2 - ab - 3b^2 ), you need specific values for ( a ) and ( b ). Without those values, the expression can be simplified or factored, but it cannot be evaluated to a numerical value. If you provide values for ( a ) and ( b ), I can help calculate the result.
( 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.
