You find the LCM of the denominators in the fractions, then you multiply both fractions as needed till both have like denominators. Then you subtract.
For example:
5/9 - 2/4
LCM of 9 and 4 is 36
[(5 x 4)/(9 x 4)] - [(2 x 9) - (4 x 9)]
= 20/36 - 18/36
20/36 - 18/36 = 2/36
2/36 = 1/18
hope this helps ya!

The answer is D. 3x^3+4x^2-11x+3
H(h(x)) means to use the entire function h(x) as the x value in the function h(x)..
h(h(x)) = (x²+1)² + 1
= (x²+1)(x²+1) + 1
= (x^4 + x² + x² + 1) + 1
= x^4 + 2x² + 2
g(h(x)) means to use the entire function h(x) as the x value in the function g(x)..
g(h(x)) = 3(x² + 1)
= 3x² + 3
g(h(x))
