\"Simplify:
\n" ); document.write( "(x+2)(x-1)\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I assume you mean use the foil method.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(x + 2)(x - 1)
\n" ); document.write( "= x(x) + x(-1) + 2(x) + 2(-1) {used foil method}
\n" ); document.write( "= x^2 - x + 2x - 2 {multiplied through}
\n" ); document.write( "= x^2 + x - 2 {combined like terms}
