Solution for (7u+4w-2)(5u-w)=0 equation: 


Simplifying
(7u + 4w + -2)(5u + -1w) = 0

Reorder the terms:
(-2 + 7u + 4w)(5u + -1w) = 0

Multiply (-2 + 7u + 4w) * (5u + -1w)
(-2(5u + -1w) + 7u * (5u + -1w) + 4w * (5u + -1w)) = 0
((5u * -2 + -1w * -2) + 7u * (5u + -1w) + 4w * (5u + -1w)) = 0
((-10u + 2w) + 7u * (5u + -1w) + 4w * (5u + -1w)) = 0
(-10u + 2w + (5u * 7u + -1w * 7u) + 4w * (5u + -1w)) = 0

Reorder the terms:
(-10u + 2w + (-7uw + 35u2) + 4w * (5u + -1w)) = 0
(-10u + 2w + (-7uw + 35u2) + 4w * (5u + -1w)) = 0
(-10u + 2w + -7uw + 35u2 + (5u * 4w + -1w * 4w)) = 0
(-10u + 2w + -7uw + 35u2 + (20uw + -4w2)) = 0

Reorder the terms:
(-10u + -7uw + 20uw + 35u2 + 2w + -4w2) = 0

Combine like terms: -7uw + 20uw = 13uw
(-10u + 13uw + 35u2 + 2w + -4w2) = 0

Solving
-10u + 13uw + 35u2 + 2w + -4w2 = 0

Solving for variable 'u'.
