I need to name this polynomial. y=(x+4)(x+1)(x-3)

Would it be a cubic polynomial because it's all multiplying, or would it be a linear?

Pleaseexplainit to me..

Thanks:)

The terms "cubic" and "linear" refer to the form of a polynomial that is a sum of monomials. A monomial is a coefficient multiplied by some power of x. Therefore, to decide if this polynomial is cubic or linear, you have to multiply through and to represent this polynomial as a sum of powers of x with some coefficients.

Note, however, that whether it is cubic or linear depends only on the highest power of any monomial, so you don't need to find the coefficients. - Jul 19th 2012, 06:26 AMHallsofIvyRe: Naming Polynomials
It all depends on the

**meanings**of "cubic" and "linear". Do you know what those mean?
