" Q."59" if a ">0" and "b^(2)-4ac=0" ,then the graph of "y=ax^(2)+bx+c

If a>0 and b^(2)-4ac=0, then the graph of y=ax^(2)+bx+c touches x -axis and lies above x -axis.

if a gt 0 and b^2 - 4ac =0 , then the curve y= ax^2 +bx +c

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

If a,b,c are rational,if b^(2)-4ac=0 then nature of the roots of the equation ax^(2)+bx+c=0(a!=0) are

If f(x) = a + bx + cx^(2) where c > 0 and b^(2) - 4ac < 0 . Then the area enclosed by the coordinate axes,the line x = 2 and the curve y = f(x) is given by

If f(x) = a + bx + cx^(2) where c > 0 and b^(2) - 4ac < 0 . Then the area enclosed by the coordinate axes,the line x = 2 and the curve y = f(x) is given by

If alpha,beta are the roots of ax^(2)+bx+c=0 then those of ax^(2)+2bx+4c=0 are

In the equation ax^(2)+bx+c=0 , it is given that D=(b^(2)-4ac)gt0. Then, the roots of the equation are
