Does anyone know how the three squares are filled? I do not know what it means what I marked in blue

The Blue Line Marked represents How much you wish to get paid? In the first square you decide in what currency you want to get paid for example US dollars, pesos, euros, etc. In the second square you decide how much you want it get paid. In the third you decide when you want to get paid. Square 2 and 3 go together for example if you want to get paid $20 and hour our $1000 a week

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
