If it has equal roots , then D=0. That is, b*b-4ac=0. Then answer comes out to be Y=0.
Y-2
0 and 2
b^2-4ac=0
Then the value of y=0
y=2 or y=0
α+β= -b/a…… 2α=-b/a (Since α=β )… {{2α= -(3^3-y – 15)/9…….1}}….. α*β= c/a….α^2=c/a….. α^2=4/9… α=2/3…. Now from equation 1 and 2…. [[4/3= -(3^3-y -15)/9]]]……[[12= -3^3-y +15]]….[[[3^3-y=3]]]] compairing the power of 3 of both sides we get (3-y=1)… (Y =2) answer….
Y=2&0
Y=0
y=2,0
y=0 or 2.
o ans

Y=0, 2
2,0
Y = 2..
