Answer:

13x^2 -7x -6

Explanation:

(9x^2-7x) - (-4x^2+6)
after organizing subtracting these will be difficult so we will switch
---

(9x^2-7x) + (4x^2-6)
remember that the numbers after the subtract sign either be negative to positive or vis versa
---
adding it as normal
9x^2+4x^2
-7x+0
0+(-6)

13x^2 -7x -6
ax^2 -bx +c
