Answer: 47
Step-by-step explanation:
ATQ
x + 1/x = 7
Then squaring both sides we get,
x^2 + (1/x)^2 + 2 (x)(1/X) = 49
X^2 + 1/x^2 = 49-2
= 47
Hope it helps
When we use the identity (a+b)^2 formula we get a^2+b^2+2ab...
ok
So when we multiply X and 1/X it is equal to one cuz X gets cancelled so 2 multiplied to 1 is 2 .
thx
hiii
