(7u-2)(u-1)=0

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

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

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

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

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

Combine like terms: -2u + -7u = -9u
(2 + -9u + 7u2) = 0

Solving
2 + -9u + 7u2 = 0

Solving for variable 'u'.
