Hello,
\n" ); document.write( "First multiply by (p-4) to get:
\n" ); document.write( "81=p^2-8p+16
\n" ); document.write( "Subtract 81:
\n" ); document.write( "0=p^2-8p-65
\n" ); document.write( "Factor:
\n" ); document.write( "(p-13)(p+5)=0
\n" ); document.write( "Solve for p:
\n" ); document.write( "p=13
\n" ); document.write( "p=-5
