Solution for (15-x)(3-x)=(x-2)(x+1) equation: 


Simplifying
(15 + -1x)(3 + -1x) = (x + -2)(x + 1)

Multiply (15 + -1x) * (3 + -1x)
(15(3 + -1x) + -1x * (3 + -1x)) = (x + -2)(x + 1)
((3 * 15 + -1x * 15) + -1x * (3 + -1x)) = (x + -2)(x + 1)
((45 + -15x) + -1x * (3 + -1x)) = (x + -2)(x + 1)
(45 + -15x + (3 * -1x + -1x * -1x)) = (x + -2)(x + 1)
(45 + -15x + (-3x + 1x2)) = (x + -2)(x + 1)

Combine like terms: -15x + -3x = -18x
(45 + -18x + 1x2) = (x + -2)(x + 1)

45 + -18x + 1x2 = (-2 + x)(x + 1)

Reorder the terms:
45 + -18x + 1x2 = (-2 + x)(1 + x)

Multiply (-2 + x) * (1 + x)
45 + -18x + 1x2 = (-2(1 + x) + x(1 + x))
45 + -18x + 1x2 = ((1 * -2 + x * -2) + x(1 + x))
45 + -18x + 1x2 = ((-2 + -2x) + x(1 + x))
45 + -18x + 1x2 = (-2 + -2x + (1 * x + x * x))
45 + -18x + 1x2 = (-2 + -2x + (1x + x2))
