Best ResponseYou've already chosen the best response.0You can factor by grouping... \[4y^211y3=0\] \[4y^212y+y3=0\] Remove a 3 from the first 2 terms. \[4y(y3)+(y3)=0\] Factor out a (y3) \[(y3)(4y+1)=0\] Easy to find the zeroes from here.

Best ResponseYou've already chosen the best response.0Why do I have to remove a 4y from the first 2 terms? And why is it now (y3)(4y + 1)?
