Solution for (8u+5)(u-3)=0 equation:


Simplifying
(8u + 5)(u + -3) = 0

Reorder the terms:
(5 + 8u)(u + -3) = 0

Reorder the terms:
(5 + 8u)(-3 + u) = 0

Multiply (5 + 8u) * (-3 + u)
(5(-3 + u) + 8u * (-3 + u)) = 0
((-3 * 5 + u * 5) + 8u * (-3 + u)) = 0
((-15 + 5u) + 8u * (-3 + u)) = 0
(-15 + 5u + (-3 * 8u + u * 8u)) = 0
(-15 + 5u + (-24u + 8u2)) = 0
