If `(4a+c)^2 le 4b^2` then one root of `ax^2 + bx + c = 0` lies in

If (4a+c)^(2)<=4b^(2) then one root of ax^(2)+bx+c=0 lies in

If a=c=4b , then the roots of ax ^(2) + 4 bx + c =0 are

Suppose a, b, c in R, a ne 0. If a + |b| + 2c = 0 , then roots of ax^(2) + bx + c = 0 are

If 2a+3b+6c=0, then prove that at least one root of the equation ax^(2)+bx+c=0 lies in the interval (0,1) .

If 2a+3b+6c=0 , then at least one root of the eqution ax^2+bx+c=0 lies in the interval
