Practice problem
Subtract the following polynomials: 4x3+2x2+1x+9−2x3+2x2+2x−9\begin{align}\\ 4x^{3}+2x^{2}+1x&+9\\ -2x^{3}+2x^{2}+2x&-9\\ \end{align}4x3+2x2+1x−2x3+2x2+2x+9−9
2x3+4x2+3x2x^{3}+4x^{2}+3x2x3+4x2+3x
6x3−x+186x^{3}-x+186x3−x+18
6x3−x6x^{3}-x6x3−x
2x3−x+182x^{3}-x+182x3−x+18
Type a concept, like “slope” or “photosynthesis”.
