(x-7)(x-1)=

Solution for (x-7)(x-1)= equation:

Simplifying
(x + -7)(x + -1) = 0

Reorder the terms:
(-7 + x)(x + -1) = 0

Reorder the terms:
(-7 + x)(-1 + x) = 0

Multiply (-7 + x) * (-1 + x)
(-7(-1 + x) + x(-1 + x)) = 0
((-1 * -7 + x * -7) + x(-1 + x)) = 0
((7 + -7x) + x(-1 + x)) = 0
(7 + -7x + (-1 * x + x * x)) = 0
(7 + -7x + (-1x + x2)) = 0

Combine like terms: -7x + -1x = -8x
(7 + -8x + x2) = 0

Solving
7 + -8x + x2 = 0

Solving for variable 'x'.

7 + -7 + -1x = 0 + -7

Combine like terms: 7 + -7 = 0
0 + -1x = 0 + -7
-1x = 0 + -7

Combine like terms: 0 + -7 = -7
-1x = -7

Divide each side by '-1'.
x = 7

Simplifying
x = 7
Solution
x = {1, 7}
