Question

Write the polynomial in standard form. Then choose the name of the polynomial based on its degree and number of terms.

-5+ x² + x
A x + x2 - 5; cubic trinomial
B. -5 + x2 + x3; cubic trinomial
C. x + x2 - 5. quadratic trinomial
D. -5 + x2 + xo: quadratic trinomial

Answer 1

The polynomial -5+ x² + x can be written in standard form as x² + x - 5. It is a quadratic trinomial because it has three terms and the highest degree term is x², which is degree 2.

Step-by-step explanation:

The given polynomial -5+ x² + x can be written in standard form as x² + x - 5. It is a quadratic trinomial because it has three terms and the highest degree term is x², which is degree 2.

Answer 2

C. x + x² - 5. quadratic trinomial

Step-by-step explanation:

The expression -5+ x² + x is already simplified so we only need to rearrange the terms.

The standard form for a quadratic equation is ax² + bx +c. We knowits quadratic because of "x²".

-5+ x² + x => x² + x - 5

The degree is 2 because the degree of an equation is the greatest exponent on the variable(s) in one of the terms.

Between x², x and -5, x² has the greatest exponent of 2.
