All we have to do is plug in m+1 for every x in the problem.
\n" ); document.write( "f(x) = x^2+3x
\n" ); document.write( "f(m+1) = (m+1)^2+3(m+1) foiling and distributing we get
\n" ); document.write( " = m^2+2m+1+3m+3 Simplifying you get
\n" ); document.write( " = m^2+5m+4\r
\n" ); document.write( "\n" ); document.write( "and where done, unless your teacher wants it in factored form then its (m+1)(m+4).
\n" ); document.write( " \n" ); document.write( "
