Question

solve for all values of x by factoring.

x² + 8x - 4 = -4

Explanation:

Step1: Simplify the equation

Add 4 to both sides: $x^2 + 8x = 0$

Step2: Factor the left side

Factor out $x$: $x(x + 8) = 0$

Step3: Solve for x

Set each factor to 0: $x = 0$ or $x + 8 = 0$ → $x = -8$

Answer:

0, -8
