Step 2: She did not simplify under the square root correctly

under the square root:

(-6)^2 =36

and -4(5)(-8) =160

therefore under the square root it needs to be square root of 36+160 which is square root of 196.

That answer is 14 when square rooted

Solving for x...
$\frac{1}{2} x+ \frac{1}{4} = \frac{15}{16} 
$

Times the $\frac{1}{2}$ , both the numerator and denominator, by 8 to get the denominator to 16.
Times the $\frac{1}{4}$ , both the numerator and denominator, by 4 to get the denominator to 16.

Then rewrite the problem,
$\frac{8}{16}x+ \frac{4}{16} = \frac{15}{16}$

now that the denominators are all the same, you can solve...
subtract the $\frac{4}{16}$ from both sides

you should get $\frac{8}{16} x = \frac{11}{16}$

Multiply both sides by 16 (it'll cancel both the 16 out making it go away)
8x = 11

divide each side by 8 to have the x alone

8x = 11
 8 8

 You should end with x = $\frac{11}{8}$ or 1.375
