- Multiply (-2x-4) by -5:

[(-5)(-2x) + (-5)(-4)] +5x - 4 = -29

= 10x+20+5x-4=-29

- Combine Like Terms:

(10x+5x) + (20-4) = -29

15x+16=-29

- Subtract 16 from each side

15x+16 -16 = -29 -16

15x = -45

x = -3

The factored form of an equation is done by rewriting the equation in simpler forms.

The completely factored form of $x^3 - 64x$ is $x(x-8)(x + 8)$
