$(3 t^{2} - 5 t + 6) + (- 8 t^{2} + 7 t - 9)$

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

Subtract $8 t^{2}$ from $3 t^{2}$ .

$- 5 t^{2} - 5 t + 6 + 7 t - 9$

Step 3

Add $- 5 t$ and $7 t$ .

$- 5 t^{2} + 2 t + 6 - 9$

Step 4

Subtract $9$ from $6$ .

$- 5 t^{2} + 2 t - 3$
