Solution for (u-6)(u-9)=0 equation:


Simplifying
(u + -6)(u + -9) = 0

Reorder the terms:
(-6 + u)(u + -9) = 0

Reorder the terms:
(-6 + u)(-9 + u) = 0

Multiply (-6 + u) * (-9 + u)
(-6(-9 + u) + u(-9 + u)) = 0
((-9 * -6 + u * -6) + u(-9 + u)) = 0
((54 + -6u) + u(-9 + u)) = 0
(54 + -6u + (-9 * u + u * u)) = 0
(54 + -6u + (-9u + u2)) = 0

Combine like terms: -6u + -9u = -15u
(54 + -15u + u2) = 0

Solving
54 + -15u + u2 = 0

Solving for variable 'u'.
