Which expression is a quadratic binomial? 3 x 4 −2x x 2 −9x 2 x 4 +9 x 2 −6x−1 7x² !

To solve the problem shown above it is important to know that a binomial is a polynomial that has two terms. When the highest exponent of the binomial is 2, it is a binomial with degree 2, this is also called or know as "quadratic binomial". Therefore, keeping this on mind, you must identify which of the polynomial above has degree 2.

 As you can see, the answer is: −6x−1 7x²

Really any number between them works. for example 144.951
