9x2+11x-14 = (9x-7)(x+2) when factored with the help of the quadratic equation formula.
9x2-9x-10 = (3x+2)(3x-5) when factored
9x2...I guess that means 9x squared ? The problem: 9x(squared)+12x+4 Here's the answer: (3x+2)(3x+2) or even more simplified: (3x+2) squared
Divide all terms by 2 it is then x2-15+56 = (x-7)(x-8) when factored
(3x)^(2-4) = (3x)^-2 = (9x2)^-1 = 1/(9x2)
Factorising, we have, 9x2+ 30x + 25 = (3x + 5)2;thus, when y = 0, x = -1⅔. This tells us that the sole x-intercept of this function is at the vertex, (0, 1⅔).
If you mean: 9x2+3x-2 = (3x+2)(3x-1) when factored
3x(x - 2)
That can be factored to (3x - 5)(3x - 5) or (3x - 5)2
Two possibilities here. 9x - 30x +25 = -21x + 25 and done, but I don't think you mean that. 9x² - 30x + 25 is more likely. This is easier than normal, since this follows the square pattern. (ax-b)² = a²x²-2ab+b² a² = 9 so a=3 b² = 25 so b=5 3*5*2 = 30, so it checks. (3x-5)(3x-5) = 9x² -15x - 15x + 25 = 9x² -30x + 25 ■
9x2+11x-14 = (9x-7)(x+2) when factored with the help of the quadratic equation formula.
This type of statement is called a difference of squares. If you see an equation in the form:a2 - b2then it is also equal to:(a + b)(a - b)In this case 9x2, and 25 are both perfect squares. 9x2 is equal to (3x)2 and 25 is equal to 52, so the that statement can be factored out as:(3x - 5)(3x + 5)

9x^2 +6 +1 is (3x+1)(3x+1) when factored
Divide all terms by 5 and so x^2+6x-55 = (x+11)(x-5) when factored
