(7y-2) (5y²-3y+2) = 0
7y-2 = 0
y = 2/7
also
5y² - 3y + 2 = 0
Discriminate D = (-3)² - 4×5×2
= 9-40
= -31 < 0
Hence no real root exist
therefore y = 2/7
Aaryadeep:
what is question ?
wrong answer
what is answer
35 y ^ 3 - 31 y ^ 2 + 20 y -4
i have got the answer
so you just have to multiply it
I have reported your answer
ok
no problem

Answer:
=)7y-2=0
=)y=7/2

=)5y^2-3y+2=0
=)D=(-3)^2-4*5*2
=)9-40
=)-31/0
therefore 2/7
