Solution for (7u-4v-2)(2u+1)=0 equation: 


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

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

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

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

Reorder the terms:
(-2 + -4u + 7u + 14u2 + (-8uv + -4v)) = 0
(-2 + -4u + 7u + 14u2 + (-8uv + -4v)) = 0
