Let same number of hours = x,
since the salary earned is also the same, then
Salary of supervisor A = $25x
Salary of supervisor B = $20(30)+$30(x-30)
Equating
25x=600+30(x-30)
30x-25x=900-600
5x=300
x=60 hours
Check:
Salary of supervisor A = 25*60=1500
Salary of supervisor B = 20*30+30*(60-30)=600+900=1500, ok.

Answer:

$\frac{(a + b)^{2} }{a - 2 {b}^{2} } = \frac{ {(6 + ( - 8))}^{2} }{6 - 2 {( - 8)}^{2} } = \frac{(6 - 8)^{2} }{6 - 2(64)} \\ \\ = \frac{( - 2)^{2} }{6 - 128} = \frac{4}{ - 122} = - 0.032787$
