Write the polynomial in standard form. then name the polynomial based on it's degree and number of terms.

8 - 4x^2 + 10x^2 + 2x

a 14x^2 + 2x + 8, quadratic trinomial
b 6x^2 + 10x^2 + 2x, quadratic binomial
c 6x^2 + 2x + 8, quadratic trinomial
d 8x^3 + 8, cubic binomial

ANSWER

c. 6x^2 + 2x + 8, quadratic trinomial

EXPLANATION

The given polynomial is

We regroup the terms to get;

Simplify now to obtain:

This is a quadratic polynomial function based on the degree.

It is also a trinomial based on the number of terms.

The correct answer is C

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
