Answer 1

To solve this, we are going to expand our expression; in other word, we are going to multiply both binomials and simplify:
$f(x)=(3x+3)(5x-2)$
$f(x)=15x^2-6x+15x-6$
$f(x)=15x^2+9x-6$

We can conclude that the function is quadratic, also:
$15x^2$ is the quadratic term
$9x$ is the linear term
$-6$ is the constant term
