(4k+2)(k-2)/(k^2-4)(2k+1)

=2(2k+1)(k-2)/ (k^2-2^2)(2k+1)

Cancel out 2k+1

2(k-2)/(k-2)(k+2) using a^2-b^2=(a-b)(a+b)

cancel out k-2

2/k+2


Therefore numerator is 2

Given that f(x) = x2 − 3x + 3 and g(x) = the quantity of x minus one, over four, solve for f(g(x)) when x = 5.
Katena32 [7]

g(x) = the quantity of x minus one, over four

g(x) = (x-1)/4

g(5) = (5-1)/4

g(5) = 4/4

g(5) = 1


f(x) = x2 − 3x + 3

f(g(5)) =1^2 − 3(1) + 3

f(g(5)) = 1 - 3 + 3

f(g(5)) = 1
