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)
