Solution for (U+7)(U-5)= equation:


Simplifying
(U + 7)(U + -5) = 0

Reorder the terms:
(7 + U)(U + -5) = 0

Reorder the terms:
(7 + U)(-5 + U) = 0

Multiply (7 + U) * (-5 + U)
(7(-5 + U) + U(-5 + U)) = 0
((-5 * 7 + U * 7) + U(-5 + U)) = 0
((-35 + 7U) + U(-5 + U)) = 0
(-35 + 7U + (-5 * U + U * U)) = 0
(-35 + 7U + (-5U + U2)) = 0

Combine like terms: 7U + -5U = 2U
(-35 + 2U + U2) = 0

Solving
-35 + 2U + U2 = 0

Solving for variable 'U'.
