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


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

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

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

Multiply (-9 + w) * (-9 + w)
(-9(-9 + w) + w(-9 + w)) = 0
((-9 * -9 + w * -9) + w(-9 + w)) = 0
((81 + -9w) + w(-9 + w)) = 0
(81 + -9w + (-9 * w + w * w)) = 0
(81 + -9w + (-9w + w2)) = 0

Combine like terms: -9w + -9w = -18w
(81 + -18w + w2) = 0

Solving
81 + -18w + w2 = 0
