Question

if two of the zeros of the polynomial x^3+2x^2-x-2 are 1 and -1 then find all the zeros of the polynomial​

Answer 1

Here Work done=Heat

Current=I=10A

Time=t=10s

Potential difference=V=15V

We know

\boxed{\sf Heat=VIt}

Heat=VIt

\begin{gathered}\\ \sf\longmapsto H=15\times 10\times 10\end{gathered}

⟼H=15×10×10

\begin{gathered}\\ \sf\longmapsto H=15\times 100\end{gathered}

⟼H=15×100

\begin{gathered}\\ \sf\longmapsto H=1500J\end{gathered}

⟼H=1500J

Work done here is 1500Joules
