Solution for (5y-7)(y-1)= equation:


Simplifying
(5y + -7)(y + -1) = 0

Reorder the terms:
(-7 + 5y)(y + -1) = 0

Reorder the terms:
(-7 + 5y)(-1 + y) = 0

Multiply (-7 + 5y) * (-1 + y)
(-7(-1 + y) + 5y * (-1 + y)) = 0
((-1 * -7 + y * -7) + 5y * (-1 + y)) = 0
((7 + -7y) + 5y * (-1 + y)) = 0
(7 + -7y + (-1 * 5y + y * 5y)) = 0
(7 + -7y + (-5y + 5y2)) = 0

Combine like terms: -7y + -5y = -12y
(7 + -12y + 5y2) = 0
