(2x + 3) (x + 5) = x

Reorder the terms:

(3 + 2x) (x + 5) = x

Reorder the terms:

(3 + 2x) (5 + x) = x

Multiply (3 + 2x) * (5 + x)

(3 (5 + x) + 2x * (5 + x)) = x

((5 * 3 + x * 3) + 2x * (5 + x)) = x

((15 + 3x) + 2x * (5 + x)) = x

(15 + 3x + (5 * 2x + x * 2x)) = x

(15 + 3x + (10x + 2x2)) = x
