Answer

5x^{2}-9x-3$

Work Step by Step

We are given the expression $(4x^{2}-6x+2)-(-x^{2}+3x+5)$. We can subtract the second polynomial from the first polynomial by adding the opposite of the second polynomial to the first polynomial. $(4x^{2}-6x+2)+(x^{2}-3x-5)$ We can combine like terms to simplify. $(4x^{2}+x^{2})+(-6x-3x)+(2-5)=5x^{2}-9x-3$
