Answer:
- x² + 7
Step-by-step explanation:
A quadratic polynomial has the form ax² + bx + c where a, b, c are constants
Definition of a quadratic binomial
A quadratic binomial quadratic with two terms. It must always have an x² term (since a cannot equal zero in a quadratic) and one other term: either an x term (linear) or a constant term that has a nonzero coefficient.
So it is either of the form ax² + bx or ax² + c
In this case, the coefficient is a = -1 and constant is c= 7
So the quadratic binomial is
-1x² + 7 = - x² + 7
