Solution for 5+2x-3x^2=3*(3+x)*(2-x) equation:


Simplifying
5 + 2x + -3x2 = 3(3 + x)(2 + -1x)

Multiply (3 + x) * (2 + -1x)
5 + 2x + -3x2 = 3(3(2 + -1x) + x(2 + -1x))
5 + 2x + -3x2 = 3((2 * 3 + -1x * 3) + x(2 + -1x))
5 + 2x + -3x2 = 3((6 + -3x) + x(2 + -1x))
5 + 2x + -3x2 = 3(6 + -3x + (2 * x + -1x * x))
5 + 2x + -3x2 = 3(6 + -3x + (2x + -1x2))

Combine like terms: -3x + 2x = -1x
5 + 2x + -3x2 = 3(6 + -1x + -1x2)
5 + 2x + -3x2 = (6 * 3 + -1x * 3 + -1x2 * 3)
5 + 2x + -3x2 = (18 + -3x + -3x2)
