(y-6)(y-4)=0

Solution for (y-6)(y-4)=0 equation:

Simplifying
(y + -6)(y + -4) = 0

Reorder the terms:
(-6 + y)(y + -4) = 0

Reorder the terms:
(-6 + y)(-4 + y) = 0

Multiply (-6 + y) * (-4 + y)
(-6(-4 + y) + y(-4 + y)) = 0
((-4 * -6 + y * -6) + y(-4 + y)) = 0
((24 + -6y) + y(-4 + y)) = 0
(24 + -6y + (-4 * y + y * y)) = 0
(24 + -6y + (-4y + y2)) = 0

Combine like terms: -6y + -4y = -10y
(24 + -10y + y2) = 0

Solving
24 + -10y + y2 = 0

Solving for variable 'y'.

6 + -1y = 0

Move all terms containing y to the left, all other terms to the right.

Add '-6' to each side of the equation.
6 + -6 + -1y = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1y = 0 + -6
-1y = 0 + -6

Combine like terms: 0 + -6 = -6
-1y = -6

Divide each side by '-1'.
y = 6

Simplifying
y = 6
Solution
y = {4, 6}
