Factor the expression x squared - eighty one?
This is a difference of two square, so you can apply the factoring rule for the difference of two squares.
What is the formula for ml to mg?
There is no general conversion, since they measure different things (volume versus mass). You need to know the density of a specific material to do the conversion for that material, and apply the formula: mass = volume x density
What percent increase is 12 to 18?
Apply the formula of percent increase,which is : new value - old value / old value so, your question is what percent increase is 12 to 18, here 18 is the new value and 12 is the old value, now apply to the formula: percent increase= 18-12 / 12 = 0.5 now to get the percent multiply by 100 , 0.5*100 = 50% So, the percent increase 12 to 18 is 50%.
What formula do you use to calculate income tax?
To calculate income tax, one should sum up the totals of all the taxable income and subtract from it the personal allowance and any other tax free allowances. After that, one should apply the rate of tax on the resultant value to find out the income tax payable.
What is the factor of 0.9?
Factors apply to whole numbers, not decimals.
Is it possible to apply the procedures in factoring quadratic trinomials to factoring the difference of two terms?
Yes, simply treat the middle coefficient as 0.
What mathematical principles did you apply to each Quadratic Equation in Standard Form?
The mathematical principles applied to each Quadratic Equation in Standard Form include factorization or factoring, variation(correlation of variables), monomial rules, domain and range.
What quadratic function would be used to solve -2x2 plus 9x equals 12?
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
When will you apply surds in real life?
You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.
What are the roots of the equation 2xsquare -4x -1 0?
I suggest you apply the quadratic formula (a = 2, b = -4, c = -1).
How do you simplify quadratic equations?
You can combine equivalent terms. You should strive to put the equation in the form ax2 + bx + c = 0. Once it is in this standard form, you can apply the quadratic formula, or some other method, to solve it.
How do I answer this physics question using the quadratic formula?
To answer a physics question using the quadratic formula, first identify the equation that represents the problem. If the equation is in the form of ax^2 + bx + c = 0, you can apply the quadratic formula: x = [-b ± sqrt(b^2 - 4ac)] / 2a. Solve for x using this formula to find the solutions to the equation, which may represent physical quantities such as time, distance, or velocity.
How To Factor Trinomials?
Find one factor by substituting in values, then use long division. You can then apply the quadratic formula to the result - or factorise it by sight, of course
What does factoring rates mean?
Factoring rates apply to the practice of businesses selling receivables at a discount to a factor, who then collects the funds. The factoring rate is the amount of the discount at which the receivable is purchased.
What are the Order of Operations when simplifying a negative square root if using the quadratic formula to solve a quadratic formula?
The usual rules for "order of operation" apply. Don't forget that the square root of a negative number is an imaginary number. As an example, the square root of -9 is 3i (that is, the square root of +9, times the "imaginary unit").
What is the symbolic answer to x2-4x-32 equals 0?
Assuming that "x2" means x squared (x^2): x^2 - 4x - 32 = 0 factoring* (x-8)(x+4) = 0 So the roots are 8 and -4. Sorry I'm not sure what you mean by "symbolic answer." *If you don't see how to factor this trinomial, you can still apply the quadratic formula to get the same answer without being "clever."
How would you apply a factoring formula to completely factor the expression x4 - 1?
