2(x+1) (x+3)+8= (2x+1) (x+5)
\n" ); document.write( "2(x^2 + 4x + 3) + 8 = (2x^2 + 11x + 5)
\n" ); document.write( "2x^2 + 8x + 6 + 8 = 2x^2 + 11x + 5
\n" ); document.write( "Collect like terms
\n" ); document.write( "2x^2 - 2x^2 + 8x - 11x + 14 - 5 = )
\n" ); document.write( "-3x + 9 = 0
\n" ); document.write( " -3x = -9
\n" ); document.write( " x = 3
\n" ); document.write( "Proof:
\n" ); document.write( "2(x+1) (x+3)+8= (2x+1) (x+5)
\n" ); document.write( "2(3 + 1)(3 + 3) + 8 = (6 + 1)(3 + 5)
\n" ); document.write( " 2 * 4 * 6 + 8 = 7 * 8
\n" ); document.write( " 56 = 56
\n" ); document.write( "Hope this helps.
