Answer:
The zeroes of the given equation are x = √2 , -√2 , 2 , -2.
Step-by-step explanation:
The given quadratic equation is <u>y =
</u>
To find the zeroes , put y = 0.
= 0
Put
=t
The new equation is 
On factorising ,

Hence t = 2 or t = 4
On resubstituting the value of t in terms of x ,
= 2 or
= 4
Taking square root of above equation , we get
x = √2,-√2,2,-2
These are the 4 roots of the given equation .
