Question

if x square + 2x-9=0 then the roots of equation​

Answer 1

Step-by-step explanation:

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.
