Question

write the candition for real and equal root of the quadratic equation ax2+bx+c=0?​

Answer 1

Given: ax²+bx+c

To find: condition for real and  equal quadratic equation.

Step-by-step explanation:

(i) two distinct real roots, if b²-4ac > 0

(ii) two equal real roots, if b²-4ac = 0

(iii) no real roots, if b²-4ac<0

Answer: if b²-4ac = 0, then the given quadratic equation will have real and equal roots.

Answer 2

Step-by-step explanation:

When a, b and c are real numbers, a ≠ 0 and discriminant is zero (i.e., b2 - 4ac = 0),

then the roots α and β of the quadratic equation ax2 + bx + c = 0 are real and equal.
