$-7x^2-4x+4$ $quadratic$ $trinomial$

#### Work Step by Step

This is the original problem: $6x^2-13x^2-4x+4$ First of all, we need to combine like terms: $-7x^2-4x+4$ We need to put the polynomial in standard form by ordering from highest degree, to lowest. It is already in standard form. Next we need to name the polynomial. It is quadratic because the highest degree is $2$, and it is a trinomial because it has three terms. Therefore, it is a quadratic trinomial.
