Simplifying
(4u + -5)(2 + u) = 0

Reorder the terms:
(-5 + 4u)(2 + u) = 0

Multiply (-5 + 4u) * (2 + u)
(-5(2 + u) + 4u * (2 + u)) = 0
((2 * -5 + u * -5) + 4u * (2 + u)) = 0
((-10 + -5u) + 4u * (2 + u)) = 0
(-10 + -5u + (2 * 4u + u * 4u)) = 0
(-10 + -5u + (8u + 4u2)) = 0

Combine like terms: -5u + 8u = 3u
(-10 + 3u + 4u2) = 0
