(y-6)(y-3)=

Solution for (y-6)(y-3)= equation:

Simplifying
(y + -6)(y + -3) = 0

Reorder the terms:
(-6 + y)(y + -3) = 0

Reorder the terms:
(-6 + y)(-3 + y) = 0

Multiply (-6 + y) * (-3 + y)
(-6(-3 + y) + y(-3 + y)) = 0
((-3 * -6 + y * -6) + y(-3 + y)) = 0
((18 + -6y) + y(-3 + y)) = 0
(18 + -6y + (-3 * y + y * y)) = 0
(18 + -6y + (-3y + y2)) = 0

Combine like terms: -6y + -3y = -9y
(18 + -9y + y2) = 0

Solving
18 + -9y + y2 = 0

Solving for variable 'y'.

Solving
3 + -1y = 0

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

Add '-3' to each side of the equation.
3 + -3 + -1y = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1y = 0 + -3
-1y = 0 + -3

Combine like terms: 0 + -3 = -3
-1y = -3

Divide each side by '-1'.
y = 3

Simplifying
y = 3
Subproblem 2

Simplifying
6 + -1y = 0

Solving
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 = {3, 6}
