Question

Subtract these polynomials.

Answer 1

3x^2 -x^2= 2x^2
3x-2x=x
3-3=0

The answer is A.

Answer 2

Answer:

$2x^2+1x$

Step-by-step explanation:

Subtract these polynomials.  

$(3x^2 + 3x + 3) - (x^2 + 2x + 3)$

To subtract, we multiply negative sign inside the second parenthesis

$3x^2 + 3x + 3-x^2 - 2x - 3$

To subtract the polynomials we combine like terms

$3x^2-x^2+ 3x- 2x+3-3$

$2x^2+1x$
