Solution for -(y-3)(2y-5)= equation:


Simplifying
-1(y + -3)(2y + -5) = 0

Reorder the terms:
-1(-3 + y)(2y + -5) = 0

Reorder the terms:
-1(-3 + y)(-5 + 2y) = 0

Multiply (-3 + y) * (-5 + 2y)
-1(-3(-5 + 2y) + y(-5 + 2y)) = 0
-1((-5 * -3 + 2y * -3) + y(-5 + 2y)) = 0
-1((15 + -6y) + y(-5 + 2y)) = 0
-1(15 + -6y + (-5 * y + 2y * y)) = 0
-1(15 + -6y + (-5y + 2y2)) = 0

Combine like terms: -6y + -5y = -11y
-1(15 + -11y + 2y2) = 0
(15 * -1 + -11y * -1 + 2y2 * -1) = 0
(-15 + 11y + -2y2) = 0
