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

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

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

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