Write in Standard Form (x^2+8x+8)+(-10x^2+5x)

$(x^{2} + 8 x + 8) + (- 10 x^{2} + 5 x)$

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$a x^{2} + b x + c$

Subtract $10 x^{2}$ from $x^{2}$ .

$- 9 x^{2} + 8 x + 8 + 5 x$

Add $8 x$ and $5 x$ .

$- 9 x^{2} + 13 x + 8$
