Multiplying a Binomial by a Trinomial

In this video, we are going to look at how to multiply a binomial by a trinomial.
For example:
To multiply (x+6)(x^2+4x-5) we have to distribute each term in the binomial to each term in the trinomial.
When we distribute the x to the terms in the trinomial, we get x^3, 4x^2, and -5x. When we distribute the 6 to the trinomial, we get 6x^2, 24x, and -30 . So now we are left with
x^3+4x^2-5x+6x^2+24x-30
From here, we want to combine like terms, to give us a final answer of
x^3+10x^2+16x-30
