Using your own words what is the one step you do different when you subtract two functions compared to when you add two functions.
change all the signs of the second function to the opposite
f(x)=2x+3
g(x)=x2-5x+6
Solve for h(x)=f(x)*g(x)
h(x)=2x3-7x2-3x+18
f(x)=2x2+20x+41
g(x)=2x+6
Solve for h(x)=f(x)/g(x)
h(x)=(x+7)
f(x)=x3+3x2-4x-6
g(x)=x+2
Solve for h(x)=f(x)/g(x)
h(x)=x2+x-6+(6/x+2)
