Solution for (y-4)(y-3)=0 equation:


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

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

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

Multiply (-4 + y) * (-3 + y)
(-4(-3 + y) + y(-3 + y)) = 0
((-3 * -4 + y * -4) + y(-3 + y)) = 0
((12 + -4y) + y(-3 + y)) = 0
(12 + -4y + (-3 * y + y * y)) = 0
(12 + -4y + (-3y + y2)) = 0

Combine like terms: -4y + -3y = -7y
(12 + -7y + y2) = 0

Solving
12 + -7y + y2 = 0
