Solution for (u^2-2u-24)(5u+20)=0 equation: 


Simplifying
(u2 + -2u + -24)(5u + 20) = 0

Reorder the terms:
(-24 + -2u + u2)(5u + 20) = 0

Reorder the terms:
(-24 + -2u + u2)(20 + 5u) = 0

Multiply (-24 + -2u + u2) * (20 + 5u)
(-24(20 + 5u) + -2u * (20 + 5u) + u2(20 + 5u)) = 0
((20 * -24 + 5u * -24) + -2u * (20 + 5u) + u2(20 + 5u)) = 0
((-480 + -120u) + -2u * (20 + 5u) + u2(20 + 5u)) = 0
(-480 + -120u + (20 * -2u + 5u * -2u) + u2(20 + 5u)) = 0
(-480 + -120u + (-40u + -10u2) + u2(20 + 5u)) = 0
(-480 + -120u + -40u + -10u2 + (20 * u2 + 5u * u2)) = 0
(-480 + -120u + -40u + -10u2 + (20u2 + 5u3)) = 0

Combine like terms: -120u + -40u = -160u
(-480 + -160u + -10u2 + 20u2 + 5u3) = 0

Combine like terms: -10u2 + 20u2 = 10u2
(-480 + -160u + 10u2 + 5u3) = 0

Solving
-480 + -160u + 10u2 + 5u3 = 0
