X + (x + 3)(x + -3) = 3 + (x + 1)

Reorder the terms:
X + (3 + x)(x + -3) = 3 + (x + 1)

Reorder the terms:
X + (3 + x)(-3 + x) = 3 + (x + 1)

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

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

Reorder the terms:
-9 + X + x2 = 3 + (x + 1)
