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


Simplifying
(x + 3)(x + -3) = (2x2 + -15) + -1(x + 1)(x + -2)

Reorder the terms:
(3 + x)(x + -3) = (2x2 + -15) + -1(x + 1)(x + -2)

Reorder the terms:
(3 + x)(-3 + x) = (2x2 + -15) + -1(x + 1)(x + -2)

Multiply (3 + x) * (-3 + x)
(3(-3 + x) + x(-3 + x)) = (2x2 + -15) + -1(x + 1)(x + -2)
((-3 * 3 + x * 3) + x(-3 + x)) = (2x2 + -15) + -1(x + 1)(x + -2)
((-9 + 3x) + x(-3 + x)) = (2x2 + -15) + -1(x + 1)(x + -2)
(-9 + 3x + (-3 * x + x * x)) = (2x2 + -15) + -1(x + 1)(x + -2)
(-9 + 3x + (-3x + x2)) = (2x2 + -15) + -1(x + 1)(x + -2)

Combine like terms: 3x + -3x = 0
(-9 + 0 + x2) = (2x2 + -15) + -1(x + 1)(x + -2)
(-9 + x2) = (2x2 + -15) + -1(x + 1)(x + -2)

Reorder the terms:
-9 + x2 = (-15 + 2x2) + -1(x + 1)(x + -2)

Remove parenthesis around (-15 + 2x2)
-9 + x2 = -15 + 2x2 + -1(x + 1)(x + -2)

Reorder the terms:
-9 + x2 = -15 + 2x2 + -1(1 + x)(x + -2)

Reorder the terms:
-9 + x2 = -15 + 2x2 + -1(1 + x)(-2 + x)

Multiply (1 + x) * (-2 + x)
-9 + x2 = -15 + 2x2 + -1(1(-2 + x) + x(-2 + x))
-9 + x2 = -15 + 2x2 + -1((-2 * 1 + x * 1) + x(-2 + x))
-9 + x2 = -15 + 2x2 + -1((-2 + 1x) + x(-2 + x))
-9 + x2 = -15 + 2x2 + -1(-2 + 1x + (-2 * x + x * x))
-9 + x2 = -15 + 2x2 + -1(-2 + 1x + (-2x + x2))

Combine like terms: 1x + -2x = -1x
-9 + x2 = -15 + 2x2 + -1(-2 + -1x + x2)
-9 + x2 = -15 + 2x2 + (-2 * -1 + -1x * -1 + x2 * -1)
-9 + x2 = -15 + 2x2 + (2 + 1x + -1x2)

Reorder the terms:
-9 + x2 = -15 + 2 + 1x + 2x2 + -1x2

Combine like terms: -15 + 2 = -13
-9 + x2 = -13 + 1x + 2x2 + -1x2

Combine like terms: 2x2 + -1x2 = 1x2
-9 + x2 = -13 + 1x + 1x2

Solving
-9 + x2 = -13 + 1x + 1x2

Solving for variable 'x'.

Reorder the terms:
-9 + 13 + -1x + x2 + -1x2 = -13 + 1x + 1x2 + 13 + -1x + -1x2
