Practice problem
If f(x)=x3+2x2+1f(x) = x^3 + 2x^2 + 1f(x)=x3+2x2+1 and g(x)=xg(x) = xg(x)=x, find f(x)g(x)f(x) g(x)f(x)g(x).
x3+2x2+1x^3 + 2x^2 + 1x3+2x2+1
x3+2x2+x+1x^3 + 2x^2 + x + 1x3+2x2+x+1.
x4+2x3+xx^4 + 2x^3 + xx4+2x3+x
x3+2x2+xx^3 + 2x^2 + xx3+2x2+x
Type a concept, like “slope” or “photosynthesis”.
