Solve 8x^2 + 6x + 5 = 0

I'm doing square roots and all the steps but it's not working out

I come up with -0.38 + 0.5 and -0.38 - 0.5

But it's not right when I go to put it back in.

Could you please show the steps-these problems really throw me off.

Thank you

= (-6 ± √-124)/16

I will stop here, have you found your error?

There are no real roots.

If you studies complex numbers you should be able to finish it
