(g+4)(g-4)=

Solution for (g+4)(g-4)= equation:

Simplifying
(g + 4)(g + -4) = 0

Reorder the terms:
(4 + g)(g + -4) = 0

Reorder the terms:
(4 + g)(-4 + g) = 0

Multiply (4 + g) * (-4 + g)
(4(-4 + g) + g(-4 + g)) = 0
((-4 * 4 + g * 4) + g(-4 + g)) = 0
((-16 + 4g) + g(-4 + g)) = 0
(-16 + 4g + (-4 * g + g * g)) = 0
(-16 + 4g + (-4g + g2)) = 0

Combine like terms: 4g + -4g = 0
(-16 + 0 + g2) = 0
(-16 + g2) = 0

Solving
-16 + g2 = 0

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '16' to each side of the equation.
-16 + 16 + g2 = 0 + 16

Combine like terms: -16 + 16 = 0
0 + g2 = 0 + 16
g2 = 0 + 16

Combine like terms: 0 + 16 = 16
g2 = 16

Simplifying
g2 = 16

Take the square root of each side:
g = {-4, 4}
