take half of 10 and square it
x² - 10x + 25 = 11 + 25
(x-5)² = 36
x-5 = 
x - 5 = 6 and x - 5 = -6

Step-by-step explanation:
9*102-5.6*102=
102(9+5.6) =
102(9.0+5.6) =
102(14.6) =
102*14.6=
14.6*(100+2) =
(14.6*100+14.6*2) =
(1460+(14+.6) *2) =
1460+(28+1.2) =
1460+(28.0+1.2) =
1460+29.2=
1460.0+
29.2
