Answer:

Write the problem as a mathematical expression.

−2y−y2−1+x4

Rewrite x4

as (x2)2

.

−2y−y2−1+(x2)2

Rewrite 2y+y2+1

as (y+1)2

.

Tap for more steps...

−(y+1)2+(x2)2

Reorder −(y+1)2

and (x2)2

.

(x2)2−(y+1)2

Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b)

where a=x2 and b=y+1

.

(x2+y+1)(x2−(y+1))

Simplify.

(x2+y+1)(x2−y−1)

Hope this helps :))
