Question

Which of the following is a solution of x2 + 4x + 10?

Answer 1

The solution is 4x+2x=6x then 6x+10=solution

Answer 2

Answer:

The solutions are $-2+ 2\sqrt{6}\texttt{ and}-2- 2\sqrt{6}$

Step-by-step explanation:

We have to find solution of x²+4x+10.

Solution is given by

                $\frac{-4\pm \sqrt{4^2-4\times 1\times 10}}{2\times 1}=\frac{-4\pm \sqrt{16-40}}{2}=-2\pm 2\sqrt{6}$

So the solutions are $-2+ 2\sqrt{6}\texttt{ and}-2- 2\sqrt{6}$
