Help pleaseI'm doing something wrong
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 stepsthese problems really throw me off.
Thank you

x = (6 ± √(364(8)(5))/16
= (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
