Question

F(x)= (x-2)(x-3)(x-5) simplify the right side. What is the equation?

Answer 1

x³ - 10x² + 31x - 30

Explanation:

Given

(x - 2)(x - 3)(x - 5) ← expand the second pair of factors using FOIL

= (x - 2)(x² - 8x + 15) ← distribute

= x³ - 8x² + 15x - 2x² + 16x - 30 ← collect like terms

= x³ - 10x² + 31x - 30
