Solution for (u-7)(u-7)=2u^2-6u+61 equation:


Simplifying
(u + -7)(u + -7) = 2u2 + -6u + 61

Reorder the terms:
(-7 + u)(u + -7) = 2u2 + -6u + 61

Reorder the terms:
(-7 + u)(-7 + u) = 2u2 + -6u + 61

Multiply (-7 + u) * (-7 + u)
(-7(-7 + u) + u(-7 + u)) = 2u2 + -6u + 61
((-7 * -7 + u * -7) + u(-7 + u)) = 2u2 + -6u + 61
((49 + -7u) + u(-7 + u)) = 2u2 + -6u + 61
(49 + -7u + (-7 * u + u * u)) = 2u2 + -6u + 61
(49 + -7u + (-7u + u2)) = 2u2 + -6u + 61

Combine like terms: -7u + -7u = -14u
(49 + -14u + u2) = 2u2 + -6u + 61
