Solution for (4u+7)(2-u)=0 equation:


Simplifying
(4u + 7)(2 + -1u) = 0

Reorder the terms:
(7 + 4u)(2 + -1u) = 0

Multiply (7 + 4u) * (2 + -1u)
(7(2 + -1u) + 4u * (2 + -1u)) = 0
((2 * 7 + -1u * 7) + 4u * (2 + -1u)) = 0
((14 + -7u) + 4u * (2 + -1u)) = 0
(14 + -7u + (2 * 4u + -1u * 4u)) = 0
(14 + -7u + (8u + -4u2)) = 0

Combine like terms: -7u + 8u = 1u
(14 + 1u + -4u2) = 0
