WE know that equation ax
2
+bx+c=0
Then sum of roots =
a
−b
(i) In equation 2x
2
+3x+6=0
the sum roots =
2
−3
this not as3
(ii)IN equation x
2
−3x+3=0
1
−3
=3 this is 3
(iii) In equation
2
x
2
+
2
3
x=10⇒
2
x
2
+
2
3
x−10=0
Sum of roots =
2
−
2
3
=−
2
3
is not 3
(iv) In equation 3x
2
+3x+3=0
Sum of roots =
3
−3
=−1 This is not 3
Then in equation x
2
−3x+3=0 is 3
