Question

Which expression is equivalent to this polynomial?
(4x + 3)(3x-8)

Answer 1

`f(x) = (4x + 3)(3x - 8) \\ f(x) = 12 {x}^(2) - 32x + 9x - 24 \\ \boxed{f(x) = 12 {x}^(2) - 23x - 24}`

Answer 2

12x^2-23x-24

Explanation:

use foil(first, outside, inside, last):

12x^2-32x+9x-24

simplify(combine like terms):

12x^2-23x-24
