Write in Standard Form (4v^3-3v^2+2v)+(3v^3+6v^2-9v)

$(4 v^{3} - 3 v^{2} + 2 v) + (3 v^{3} + 6 v^{2} - 9 v)$

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 $4 v^{3}$ and $3 v^{3}$ .

$7 v^{3} - 3 v^{2} + 2 v + 6 v^{2} - 9 v$

Step 3

Add $- 3 v^{2}$ and $6 v^{2}$ .

$7 v^{3} + 3 v^{2} + 2 v - 9 v$

Step 4

Subtract $9 v$ from $2 v$ .

$7 v^{3} + 3 v^{2} - 7 v$
