Answer:

Step-by-step explanation:

Subtract these polynomials.  

[tex](3x^2 + 3x + 3) - (x^2 + 2x + 3)[/tex]

To subtract, we multiply negative sign inside the second parenthesis

[tex]3x^2 + 3x + 3-x^2 - 2x - 3[/tex]

To subtract the polynomials we combine like terms

[tex]3x^2-x^2+ 3x- 2x+3-3[/tex]

[tex]2x^2+1x[/tex]
