Step-by-step explanation:
(x²+1/x²)(x²-1/x²)
using (a+b)(a-b)=a²-b²
so, (x²)²-( 1/x²)²
x⁴-1/x⁴
So this is the answer
HOPE IT HELPS !!!
PLEASE GIVE 5 STARS^_^
Step-by-step explanation:
The value of (1+x)(1+x) is (1+x)
2
We know suitable identities is (x+y)
2
=x
2
+2xy+y
2
Therefore, the value of (1+x)
2
is
=(1)
2
+2(1)(x)+x
2
=1+2x+x
2
=x
2
+2x+1
