1. Factor x^2+9x+20
((x+4)(x+5))/(x+3)*(x^2-x-12)/(x^2+3x-4)

2. Factor x^2-x-12
((x+4)(x+5))(x+3)*((x-4)(x+3)/(x^2+3x-4)

3. Factor x^2+3x-4
((x+4)(x+5))/(x+3)*((x-4)(x+3))/((x-1)(x+4))

4. Simplify
((x+4)(x+5)(x-4)(x+3))/((x+3)(x-1)(x+4))

5. Cancel x+3
((x+5)(x-4))/(x-1)

Solve the equation. 8x2 – 4 = 28
Flura [38]
Hello,

Your answer would be 2, -2.

8x^2 - 4 = 28

8x^2-4+4=28+4

8x^2 = 32

\frac{8x^2}{8}=  \frac{32}{8}  


x^2 = 4

x = +/4 

x = 2 or x = -2

2 , -2 would be the answer! :)
