4x + 2h - 1

Step-by-step explanation:

$\frac{f(x+h) - f(x)}{h}$

$\frac{(2(x+h)^2 - (x + h) + 5) - (2x^2 - x + 5)}{h}$

$\frac{2x^2 + 4xh + 2h^2 - x - h + 5 - 2x^2 + x - 5}{h}$

$\frac{4xh + 2h^2 - h}{h}$

4x + 2h - 1

$9x^{2} -x + 8$

Step-by-step explanation:

$9x^{2} + 7x -2 -(8x -10)$

$=9x^{2} + 7x -2 -8x +10$

7x -8x = -x

-2 + 10 = 8

= $9x^{2} -x + 8$

Hope this helps ^-^
