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}

x^2 + 4x - 12 = 0;

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

x + 6 = 0; x = -6;

x - 2 = 0; x = 2

x = {-6, 2}

2 + 4 x 6^2 – 8

= 2 + 4 * 36 - 8

= 2 + 144 - 8

= 138

= 2 + 4 * 36 - 8

= 2 + 144 - 8

= 138

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.

-8 – 72 ÷ 9 x 4^2 + 11

= -8 – 72 ÷ 9 x 16 + 11

= -8 - 8 x 16 + 11

= -8 - 128 + 11

= -125

= -8 – 72 ÷ 9 x 16 + 11

= -8 - 8 x 16 + 11

= -8 - 128 + 11

= -125
