`If b^(2) -4ac lt 0` then the roots of the quadratic equation are…

"If" b^(2) -4ac = 0 then the roots of the quadratic equation are…

"If" b^(2) - 4ac gt 0 then the roots of the quadratic equation are…

Assertion (A) : The roots of the quadratic equation x^(2)+2x+2=0 are imaginary. Reason (R ) : If discriminant D=b^(2)-4ac lt 0 then the roots of the quadratic equation ax^(2)+bx+c=0 are imaginary.

In a quadratic equations if the value of b^(2) - 4ac =- 7 the nature of the roots of the quadratic equations:

In quadratic equation ax^(2)+bx+c=0 , if discriminant D=b^(2)-4ac , then roots of quadratic equation are:

In quadratic equation ax^(2)+bx+c=0 , if discriminant D=b^(2)-4ac , then roots of quadratic equation are:

In quadratic equation ax^(2)+bx+c=0 , if discriminant D=b^(2)-4ac , then roots of quadratic equation are:

In quadratic equation ax^(2)+bx+c=0 , if discriminant D=b^(2)-4ac , then roots of quadratic equation are:
