Solution for (w-16)(w+9)=0 equation:


Simplifying
(w + -16)(w + 9) = 0

Reorder the terms:
(-16 + w)(w + 9) = 0

Reorder the terms:
(-16 + w)(9 + w) = 0

Multiply (-16 + w) * (9 + w)
(-16(9 + w) + w(9 + w)) = 0
((9 * -16 + w * -16) + w(9 + w)) = 0
((-144 + -16w) + w(9 + w)) = 0
(-144 + -16w + (9 * w + w * w)) = 0
(-144 + -16w + (9w + w2)) = 0

Combine like terms: -16w + 9w = -7w
(-144 + -7w + w2) = 0

Solving
-144 + -7w + w2 = 0

Solving for variable 'w'.
