(2n + 5k)^2 = (2n + 5k)(2n + 5k)
Here we need to use FOIL
First - 2n * 2n = 4n^2
Outside - 2n * 5k = 10nk
Inside - 5k * 2n = 10nk
Last - 5k * 5k = 25k^2
That gives us 4n^2 + 10nk + 10nk + 25k^2, we can combine 10nk + 10nk to give 20nk, and a final equaion of 4n^2 + 20nk + 25k^2
Replace f(x) with y
switch x and y
solve for y
replace y with g(x)
y=1/3x+2
x=1/3y+2
x-2=1/3y
3x-6=y
g(x)=3x-6
f(g(x)) should have the same result as g(f(x)) which should be x
f(g(x))=1/3(3x-6)+2=x-2+2=x
g(f(x))=3(1/3x+2)-6=x+6-6=x
the inverse is g(x)=3x-6
