Answer 1

there will be 4 roots in eqn:-

Step-by-step explanation:

1. Substitute value of (y² + 3y) as any variable (eg. t)
2. then factorise 1st & 3rd term and simultaneously factorise 2nd and 4th term
3. after getting the ans by taking common variables or numbers, substitute value of t as (y²+3y)
4. Then if you still get 2 eqns, which u r unable to solve then u hv to use the determinant formul
