(x-11)(x-13)=

Solution for (x-11)(x-13)= equation:

Simplifying
(x + -11)(x + -13) = 0

Reorder the terms:
(-11 + x)(x + -13) = 0

Reorder the terms:
(-11 + x)(-13 + x) = 0

Multiply (-11 + x) * (-13 + x)
(-11(-13 + x) + x(-13 + x)) = 0
((-13 * -11 + x * -11) + x(-13 + x)) = 0
((143 + -11x) + x(-13 + x)) = 0
(143 + -11x + (-13 * x + x * x)) = 0
(143 + -11x + (-13x + x2)) = 0

Combine like terms: -11x + -13x = -24x
(143 + -24x + x2) = 0

Solving
143 + -24x + x2 = 0
