Question

factorise y²+1/y²+2-5y-5/y
​

Answer 1

Step-by-step explanation:

Your question: factorise y²+1/y²+2-5y-5/y

solution: on using identity x²+1/x²+2 = (x+1/x)²

(y+1/y)²-5y-5/y

on taking common -5 from -5y-5/y

(y+1/y)²-5(y+1/y)

on taking (y+1/y) whole common

y+1/y{y+1/y-5}

hope it helps
