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

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

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

Multiply (-1 + x2) * (3 + x)
(-1(3 + x) + x2(3 + x)) = (3x + 3)(x + 3)
((3 * -1 + x * -1) + x2(3 + x)) = (3x + 3)(x + 3)
((-3 + -1x) + x2(3 + x)) = (3x + 3)(x + 3)
(-3 + -1x + (3 * x2 + x * x2)) = (3x + 3)(x + 3)
(-3 + -1x + (3x2 + x3)) = (3x + 3)(x + 3)
(-3 + -1x + 3x2 + x3) = (3x + 3)(x + 3)
