Question

Solve y² +1/2y-1=0 by Factorisation

Answer 1

Student ,

if considering a ratio or a ratio
(a÷b)=0 given ,
this implies a=0 and b cannot be equal to zero.

this is what happened in this question also.
( 2y^3 -2y +1 ) ÷(2y) =0
implies

2y^3 -2y +1 =0 (as i told above)
no need to take the denominator there.

i think you got the idea.

so the above answer is correct

Like if satisfied.
