(x-7)*(x-6)=

Solution for (x-7)*(x-6)= equation:

Simplifying
(x + -7)(x + -6) = 0

Reorder the terms:
(-7 + x)(x + -6) = 0

Reorder the terms:
(-7 + x)(-6 + x) = 0

Multiply (-7 + x) * (-6 + x)
(-7(-6 + x) + x(-6 + x)) = 0
((-6 * -7 + x * -7) + x(-6 + x)) = 0
((42 + -7x) + x(-6 + x)) = 0
(42 + -7x + (-6 * x + x * x)) = 0
(42 + -7x + (-6x + x2)) = 0

Combine like terms: -7x + -6x = -13x
(42 + -13x + x2) = 0

Solving
42 + -13x + x2 = 0
