Reorder the terms:
(1 + x)(-2 + x)(2x + 5) = 0

Reorder the terms:
(1 + x)(-2 + x)(5 + 2x) = 0

Multiply (1 + x) * (-2 + x)
(1(-2 + x) + x(-2 + x))(5 + 2x) = 0
((-2 * 1 + x * 1) + x(-2 + x))(5 + 2x) = 0
((-2 + 1x) + x(-2 + x))(5 + 2x) = 0
(-2 + 1x + (-2 * x + x * x))(5 + 2x) = 0
(-2 + 1x + (-2x + x2))(5 + 2x) = 0

Combine like terms: 1x + -2x = -1x
(-2 + -1x + x2)(5 + 2x) = 0

Multiply (-2 + -1x + x2) * (5 + 2x)
(-2(5 + 2x) + -1x * (5 + 2x) + x2(5 + 2x)) = 0
((5 * -2 + 2x * -2) + -1x * (5 + 2x) + x2(5 + 2x)) = 0
((-10 + -4x) + -1x * (5 + 2x) + x2(5 + 2x)) = 0
(-10 + -4x + (5 * -1x + 2x * -1x) + x2(5 + 2x)) = 0
(-10 + -4x + (-5x + -2x2) + x2(5 + 2x)) = 0
(-10 + -4x + -5x + -2x2 + (5 * x2 + 2x * x2)) = 0
(-10 + -4x + -5x + -2x2 + (5x2 + 2x3)) = 0
