(y-1)(3y-4)=

Solution for (y-1)(3y-4)= equation:

Simplifying
(y + -1)(3y + -4) = 0

Reorder the terms:
(-1 + y)(3y + -4) = 0

Reorder the terms:
(-1 + y)(-4 + 3y) = 0

Multiply (-1 + y) * (-4 + 3y)
(-1(-4 + 3y) + y(-4 + 3y)) = 0
((-4 * -1 + 3y * -1) + y(-4 + 3y)) = 0
((4 + -3y) + y(-4 + 3y)) = 0
(4 + -3y + (-4 * y + 3y * y)) = 0
(4 + -3y + (-4y + 3y2)) = 0

Combine like terms: -3y + -4y = -7y
(4 + -7y + 3y2) = 0

Solving
4 + -7y + 3y2 = 0

Solving for variable 'y'.
