The second one would be the answer. You want to plug in for this question. You can divide over the five leaving you with (x-2)^2 =25. Since you are squaring this answer, you want to get either 5 or negative five. Both -3 and 7 will do that.

(x-2) ^2 = 125/5,
from formula (a-b)^2= a^2 - 2ab+ b^2
the equation becomes
x^2 - 4x+4= 25
x^2-4x-21= 0
x^2 -7x+3x-21=0
x(x-7)+3(x-7)= 0
(x+3) (x-7)= 0
so either x+3=0
or x-7=0
x can have values x= -3, 7

9 games

You can get this by multiplying each percentage by the total number of games to see what they have to expect.

.55*180 = 99 games (red team)

.60*180 = 108 games (blue team)

Now subtract the blue team expectation from the red team.

108 - 99 = 9 games.
