2x^2+x-1

Explanation:

3x^2-2x+3-(x^2-3x+4)=3x^2-2x+3-x^2+3x-4=2x^2+x-1

Simplifying the above expression gives us 2x^2+x-1

Explanation:

Before we start simplifying the expression, we need to distribute the negative sign on the right side which gives us -x^2+3x-4

So the expression we have left to simplify it further down is

3x^2-2x+3-x^2+3x-4

So we are combining like term but remember, we always rearrange the term from highest degree to lowest degree in standard form of an expression.

So simplifying the expression gives us:

2x^2+x-1
