Write in Standard Form (9x^2-8)+(9x^2+9x+3)

$(9 x^{2} - 8) + (9 x^{2} + 9 x + 3)$

Step 1

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

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

Step 2

Add $9 x^{2}$ and $9 x^{2}$ .

$18 x^{2} - 8 + 9 x + 3$

Step 3

Add $- 8$ and $3$ .

$18 x^{2} + 9 x - 5$
