Question

Simplify (x – 3)(x2 + 7x – 8)

Answer 1

x^3 + 4x^2 - 29x +24

Answer 2

Just go along the brackets and multiply each term of the first by every term of the other, then group like terms and simplify:
(x*x^2 + x*7x - 8x) - (3*x^2 + 3*7x - 3*8)
= x^3 + 7x^2 - 8x - 3x^2 - 21x + 24
= x^3 + 4x^2 - 29x + 24
