Question

The discriminant of a quadratic equation is negative. One solution is 3+4i . What is the other solution?

Answer 1

I believe the correct answer from the choices listed above is option B. The discriminant of a quadratic equation is negative. One solution is 3+4i . The other would be 3-4i. Hope this answers the question. Have a nice day.

Answer 2

Answer: Option B 3-4i is the correct option

Explanation:

we have formula for discriminant $D=b^{2}-4ac$

after that we find the required variable that is to be find according to the quadratic equation given suppose we have to find x

then we have formula $x=\frac{-b\pm\sqrt{D}} {2a}$

Here we have $\pm$ of roots if we have one root 3+41 other would be of opposite sign and hence,definitely be 3-4i.

Therefore Option B 3-4i is the correct option.
