Question

xpower3+2xpower2-x-2;x+1

Answer 1

$\begin{gathered}\\ \sf\longmapsto x {}^{3} + 2x {}^{2} \times 2 - x - 2(x + 1)\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto x ^{3} + 4x ^{2} - x - 2(x + 1)\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto x^{3} + 4x {}^{2} - x - 2x - 2\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto x^{3}+5x^{2}-3x-2\end{gathered}$

Solved ✔︎
