Write in Standard Form 18a^2b^2+7ab-b^2+4a^3

$18 a^{2} b^{2} + 7 a b - b^{2} + 4 a^{3}$

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

Move $7 a b$ .

$18 a^{2} b^{2} - b^{2} + 4 a^{3} + 7 a b$

Step 3

Move $- b^{2}$ .

$18 a^{2} b^{2} + 4 a^{3} - b^{2} + 7 a b$
