Answer 2

Answer:

1)x⁴+x²+25=(x²+2x+5)(x²-2x+5)

2)x²-1-2a-a²​=(x+a+1)(x-a-1)

Step-by-step explanation:

1)x⁴+x²+25

=x⁴+5x²-4x²+25

=(x²)²+5x²+(5)²-4x²

=(x²+5)²-(2x)²

=(x²+5+2x)(x²+5-2x)

=(x²+2x+5)(x²-2x+5)

Ans:-(x²+2x+5)(x²-2x+5)

2)x²-1-2a-a²​

=x²-(1+2a+a²)

=x²-(1+a)²

=(x+1+a)​(x-1-a)

=(x+a+1)(x-a-1)

Ans:-(x+a+1)(x-a-1)

Hope it helps you =)
