Which of the following is the solution set of x^2+8x+12=0

x = -2 , x = -6

Step-by-step explanation:

x^2 + 8x + 12 = 0

Factors

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

x + 6 = 0; x = -6

x + 2 = 0; x = -2

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
