Question

Simplify the given polynomial and use it to complete the statement.

Answer 1

Answer:

A. Quadratic

C. Binomial

B. 2

Step-by-step explanation:

The given polynomial is

$(-5x^2-2x+4)+(8x^2-x-1)-(x+2)(x-5)$

We expand the bracket to obtain;

$-5x^2-2x+4+8x^2-x-1-(x^2-5x+2x-10)$

$-5x^2-2x+4+8x^2-x-1-(x^2-3x-10)$

$-5x^2-2x+4+8x^2-x-1-x^2+3x+10$

We regroup the terms to obtain;

$-5x^2+8x^2-x^2-x+3x-2x+4+10-1$

We simplify to get;

$2x^2+13$

The polynomial simplifies to an expression that is a

A. quadratic

C. Binomial

with a degree of

B. 2
