sqrt(p^2-3p+16)=p+1 square both sides.
\n" ); document.write( "p^2-3p+16=p^2+2p+1
\n" ); document.write( "-3p-2p=1-16
\n" ); document.write( "-5p=-15
\n" ); document.write( "p=-15/-5
\n" ); document.write( "p=3 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "sqrt(3^2-3*3+16)=3+1
\n" ); document.write( "sqrt(9-9+16)=4
\n" ); document.write( "sqrt16=4
\n" ); document.write( "4=4 \n" ); document.write( "
