Question

factorise the following expression using algebraic identities:
x²+1/x²+2​

Answer 1

Answer:

Step-by-step explanation: This statement could also be written as

(x)^2+(1/x)^2+(2*x*1/x)

This form works with (a+b)^2=a^2+b^2+2ab

Therefore by factorisation we get

(x+1/x)^2

(x+1/x)(x+1/x)

Hope this helps. ✌
