Question

If the quadratic equation

+ + = has equal roots, then value of is

a) ± b) c) − d) ​

Answer 1

Answer:

When a, b, and c are real numbers, a ≠ 0 and the discriminant is zero, then the roots α and β of the quadratic equation ax 2 + bx + c = 0 are real and equal. Case III: b 2 – 4ac < 0 When a, b, and c are real numbers, a ≠ 0 and the discriminant is negative, then the roots α and β of the quadratic equation ax 2 + bx + c = 0 are unequal ..
