Question

Factorise ( x^2+1/x^2)-4(x+1/x)+6

solve this who can I will mark brainlest

Answer 1

With imaginary solutions, yes, as then it would be

(x+i)(x-i)=0

Which, with using the foil method, gets you:

x^2+xi-xi-i^2=x^2-i^2

Since i^2 equals -1, you can change the equation to be:

x^2-(-1)=x^2+1

Without imaginary solutions, however, this is unfactorable
