$11 x^{2} + 36 x + 8$ $11x^2+36x+8$

Combine all squared $x$ $x$ 's:

$11 x^{2} + 11 x + 8 + 15 x + 10 x$ $11x^2+11x+8+15x+10x$

Combine all $x$ $x$ 's:

$11 x^{2} + 36 x + 8$ $11x^2+36x+8$

Since you only have one constant, you don't need to combine anything with it, considering it has no like terms.
