1.Add the polynomials.

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

When you add polynomials, the most important thing to remember is to keep like terms (the same exponent) together.

(X^3+4x^2+2x-3)+ (-x^3-3x^2-3x+2)
1) Rewrite with like terms together: (x^3 + -x^3) + (4x^2+-3x^2)+(2x+-3x)+(-3+2)
2) Perform the addition: (0)+(x^2)+(-x)+(-1)
3) Simplify to eliminate parentheses: x^2-x-1

This is the same as number 1; the only difference is that since it is subtraction you need to remember to use the opposite signs.
1) Rewrite with like terms together: ...
