Question

Determine whether the function is linear or quadratic. Identify the quadratic, linear, and constant terms. f(x)=(3x+3)(5x-2)

Answer 1

To get your quadratic equation, you're going to want to use the FOIL method.

3x(5x) + 3x(- 2) + 3(5x) + 3(- 2)

Simplify to get
`15 x^(2) -6x+15x-6`

Combine like terms:


`15 x^(2) +9x-6`

Your quadratic term is
`15x^(2)`

Your linear term is
`9x`

Your constant is
`-6`
