Question

Determine the nature of roots. x

2 + 2x - 9 = 0​

Answer 1

Explanation: In the equation x2−2x+9=0 , the coefficients are rational but as the discriminant is (−2)2−4×1×9=4−36=−32 is negative, the roots of the equation are pair of complex conjugate numbers. Hence, we can use quadratic formula to get roots. ... Note that b2−4ac is the discriminant.
