Question

If  ax2+bx+c=0ax2+bx+c=0 is a quadratic equation and a + b + c = 0 then both the roots are -

A. 1 and a/c

B. -1 and c/a

C. 1 and c/a

D. none of these

​

Answer 1

Answer:

When D = 0, the roots are real and equal. When D < 0, the roots are imaginary. ∴ The numerator of the quadratic formula (−b±√b2−4ac) will always be negative in this problem. Both are complex with negative real parts.

Answer 2

Answer:

C. 1 and c/a is the answer
