Question

Which polynomial is equal to (2x^2-5x-4)-(4x^2-3x-2) , and how is it equal?

Answer 1

Answer:

Option A

Step-by-step explanation:

Hi.

Let's simplify the given expression:-

(2x^2-5x-4)-(4x^2-3x-2)

When we remove the second parentheses we must distribute the negative over the contents:-

= 2x^2 - 5x - 4 - 4x^2 + 3x + 2

Now adding like terms, we get:-

- 2x^2 - 2x - 2    

So it's option A

Answer 2

Answer:

A. -2x^2-2x-2

Step-by-step explanation:

(2x^2-5x-4)-(4x^2-3x-2)

distribute the minus sign

(2x^2-5x-4)-4x^2+3x+2

2x^2-5x-4

-4x^2+3x+2

-------------------------

-2x^2 -2x-2
