Write in Standard Form (x^4-2x^2y-7)+(7x^4+6xy-3)

$(x^{4} - 2 x^{2} y - 7) + (7 x^{4} + 6 x y - 3)$

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 $x^{4}$ and $7 x^{4}$ .

$8 x^{4} - 2 x^{2} y - 7 + 6 x y - 3$

Step 3

Subtract $3$ from $- 7$ .

$8 x^{4} - 2 x^{2} y + 6 x y - 10$
