(y-1)(y-6)=0

Solution for (y-1)(y-6)=0 equation:

Simplifying
(y + -1)(y + -6) = 0

Reorder the terms:
(-1 + y)(y + -6) = 0

Reorder the terms:
(-1 + y)(-6 + y) = 0

Multiply (-1 + y) * (-6 + y)
(-1(-6 + y) + y(-6 + y)) = 0
((-6 * -1 + y * -1) + y(-6 + y)) = 0
((6 + -1y) + y(-6 + y)) = 0
(6 + -1y + (-6 * y + y * y)) = 0
(6 + -1y + (-6y + y2)) = 0

Combine like terms: -1y + -6y = -7y
(6 + -7y + y2) = 0

Solving
6 + -7y + y2 = 0

Solving for variable 'y'.

Factor a trinomial.

Solving
1 + -1y = 0

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

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

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

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

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

Simplifying
y = 1
Subproblem 2
Set the factor '(6 + -1y)' equal to zero and attempt to solve:

Simplifying

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 = {1, 6}
