Solution for (2u+1)(u-4)(5u-5)=0 equation: 


Simplifying
(2u + 1)(u + -4)(5u + -5) = 0

Reorder the terms:
(1 + 2u)(u + -4)(5u + -5) = 0

Reorder the terms:
(1 + 2u)(-4 + u)(5u + -5) = 0

Reorder the terms:
(1 + 2u)(-4 + u)(-5 + 5u) = 0

Multiply (1 + 2u) * (-4 + u)
(1(-4 + u) + 2u * (-4 + u))(-5 + 5u) = 0
((-4 * 1 + u * 1) + 2u * (-4 + u))(-5 + 5u) = 0
((-4 + 1u) + 2u * (-4 + u))(-5 + 5u) = 0
(-4 + 1u + (-4 * 2u + u * 2u))(-5 + 5u) = 0
(-4 + 1u + (-8u + 2u2))(-5 + 5u) = 0

Combine like terms: 1u + -8u = -7u
(-4 + -7u + 2u2)(-5 + 5u) = 0

Multiply (-4 + -7u + 2u2) * (-5 + 5u)
(-4(-5 + 5u) + -7u * (-5 + 5u) + 2u2 * (-5 + 5u)) = 0
((-5 * -4 + 5u * -4) + -7u * (-5 + 5u) + 2u2 * (-5 + 5u)) = 0
((20 + -20u) + -7u * (-5 + 5u) + 2u2 * (-5 + 5u)) = 0
(20 + -20u + (-5 * -7u + 5u * -7u) + 2u2 * (-5 + 5u)) = 0
(20 + -20u + (35u + -35u2) + 2u2 * (-5 + 5u)) = 0
(20 + -20u + 35u + -35u2 + (-5 * 2u2 + 5u * 2u2)) = 0
(20 + -20u + 35u + -35u2 + (-10u2 + 10u3)) = 0

Combine like terms: -20u + 35u = 15u
(20 + 15u + -35u2 + -10u2 + 10u3) = 0

Combine like terms: -35u2 + -10u2 = -45u2
(20 + 15u + -45u2 + 10u3) = 0

Solving
20 + 15u + -45u2 + 10u3 = 0
