$- 10 x^{2} + 13 x - 6$ $-10x^2 + 13x - 6$

Explanation:

All you have to do is pretty much subtract the different powered variables $(E x . x^{3}, x^{2}, x)$ $(Ex. x^3, x^2, x)$
so ...
$- x^{2} - 9 x^{2} = - 10 x^{2}$ $-x^2 - 9x^2 = -10x^2$

$9 x - (- 4 x) = 13 x$ $9x - (-4x) = 13x$

$- 2 - 4 = - 6$ $-2 - 4 = -6$

Answer: $- 10 x^{2} + 13 x - 6$ $-10x^2 + 13x -6$

$(x^{2} + 9 x - 2) - (9 x^{2} - 4 x + 4) = - 8 x^{2} + 13 x - 6$ $(x^2+9x-2)-(9x^2-4x+4)=-8x^2+13x-6$

Explanation:

$(x^{2} + 9 x - 2) - (9 x^{2} - 4 x + 4)$ $(x^2+9x-2)-(9x^2-4x+4)$
$= x^{2} + 9 x - 2 - 9 x^{2} + 4 x - 4$ $=x^2+9x-2-9x^2+4x-4$
$= x^{2} - 9 x^{2} + 9 x + 4 x - 2 - 4$ $=x^2-9x^2+9x+4x-2-4$
$(1 - 9) x^{2} + (9 + 4) x - (2 + 4)$ $(1-9)x^2+(9+4)x-(2+4)$
$- 8 x^{2} + 13 x - 6$ $-8x^2+13x-6$
