Subtract: (2x2 − 9x + 2) − (−7x2 + 4x − 3)
a. - 5x^2 - 13 + 5
b. - 5x^2 - 5x + 1
c. 9x^2 - 13x + 5
d. 9x^2 - 5x + 5

The asnwer is C since the second one is infront of a negative change all the signs of ur 2nd trinomial thil will give you (7x2-4x+3) now add common like terms in the 2 trinomials 2x2 with 9x2 -9x with -4x and 2 with 3 to get 9x2 -13x+5

Hope this helps
