x^2 – 12 = - 4x;

x^2 + 4x - 12 = 0;

(x + 6)(x - 2) = 0;

x + 6 = 0; x = -6;
x - 2 = 0; x = 2

x = {-6, 2}

9. Evaluate: x^2 – 5x 3 for x = -5
Weegy: x2 ? 5x + 3 for x = -5= (-5)^2 ? 5(-5) + 3 =((-5)^2) - (5 * (-5)) + 3 = 53 User: 10. Write as a mathematical expression using parentheses and brackets. Then evaluate: Subtract 3 from 15. Divide this difference by 2. Multiply this quotient by 4. Weegy: [(15 - 3)/2] 4 User: Simplify: 5(3x + 7) Weegy: (3x-2) squared is 9x^2 - 12x + 4. (More)

factor 16x^2 – 9
Weegy: 16x^(2)-12x-10 Factor out the GCF of 2 from each term in the polynomial. 2(8x^(2))+2(-6x)+2(-5) Factor out the GCF of 2 from 16x^(2)-12x-10. 2(8x^(2)-6x-5) Find the factors such that the product of the factors is the trinomial 8x^(2)-6x-5. [ This can be done by trial and error and checked using the FOIL method of simplifying polynomials. 2(2x+1)(4x-5) ] (More)

-8 – 72 ÷ 9 x 4^2 + 11
= -8 – 72 ÷ 9 x 16 + 11
= -8 - 8 x 16 + 11
= -8 - 128 + 11
= -125
