Question

ANYONE PLEASE HELP !!!

Answer 1

2x^2 + 3

Explanation:

Subtracting functions is similar to subtracting normal numbers. An easy way to do it is to put one over the other and then combine like terms.

4x^2 + 2

- 2x^2 - 1

= 2x^2 + 3

Even though it looks like you would do 2-1, the three is because you're adding -(-1) (aka 1) to 2.

Answer 2

Explanation:

4x^2+2-2x^2-1

Group like terms:

4x^2-2x^2+2-1

2x^2+2-1

2x^2+1
