Simplifying
D = (x + 5)(2x + -3) + -3(4x + 1)

Reorder the terms:
D = (5 + x)(2x + -3) + -3(4x + 1)

Reorder the terms:
D = (5 + x)(-3 + 2x) + -3(4x + 1)

Multiply (5 + x) * (-3 + 2x)
D = (5(-3 + 2x) + x(-3 + 2x)) + -3(4x + 1)
D = ((-3 * 5 + 2x * 5) + x(-3 + 2x)) + -3(4x + 1)
D = ((-15 + 10x) + x(-3 + 2x)) + -3(4x + 1)
D = (-15 + 10x + (-3 * x + 2x * x)) + -3(4x + 1)
D = (-15 + 10x + (-3x + 2x2)) + -3(4x + 1)
