Line up the binomials (or any polynomials) as you would for multiplying large numerical values. Following the pattern of number multiplication, start with the right-hand term of the bottom binomial (+4). Multiply this value times both terms of the top binomial. Now move to the left-hand term of the bottom binomial (x).

F(x)=-9/x which is equal to:
f(x)=-9x^(-1) So the power rule for differentiation is used...
Power rule: f(x)=x^e, df/dx=ex^(e-1) so:
df/dx=-9(-1)x^(-1-1)
df/dx=9x^(-2) or if you prefer...
df/dx=9/x^2
df/dx(6)=9/36=1/4
