Write in Standard Form 9x^4-2x^2+7x-8x^3+x^5-4

$9 x^{4} - 2 x^{2} + 7 x - 8 x^{3} + x^{5} - 4$

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

Move $7 x$ .

$9 x^{4} - 2 x^{2} - 8 x^{3} + x^{5} + 7 x - 4$

Step 3

Move $- 2 x^{2}$ .

$9 x^{4} - 8 x^{3} + x^{5} - 2 x^{2} + 7 x - 4$

Step 4

Move $- 8 x^{3}$ .

$9 x^{4} + x^{5} - 8 x^{3} - 2 x^{2} + 7 x - 4$

Step 5

Reorder $9 x^{4}$ and $x^{5}$ .

$x^{5} + 9 x^{4} - 8 x^{3} - 2 x^{2} + 7 x - 4$
