$6x+8$, linear binomial.
Work Step by Step
To put a polynomial into standard form, we apply the commutative property of addition to move around the terms so that their exponents are in descending order, and then combine like terms using addition. When we do this for $7x^2+8+6x-7x^2$, we get $6x+8$. To name a polynomial, we must look at the degree and the number of terms. Since this polynomial has $2$ terms with a highest exponent of $1$, we call it a linear binomial.
