You can put this solution on YOUR website!
3x(a-3)-5(3-a)
\n" ); document.write( "---
\n" ); document.write( "3x(a-3)+5(a-3)
\n" ); document.write( "---
\n" ); document.write( "(a-3)(3x+5)
\n" ); document.write( "----------------------------------
\n" ); document.write( "20x^2-7x-6.
\n" ); document.write( "---
\n" ); document.write( "20x^2-15x+8x-6
\n" ); document.write( "---
\n" ); document.write( "5x(4x-3)+2(4x-3)
\n" ); document.write( "---
\n" ); document.write( "(4x-3)(5x+2)
\n" ); document.write( "========================
\n" ); document.write( "4x^4 + 12x^3- 28x^2
\n" ); document.write( "---------
\n" ); document.write( "4x^2[x^2+3x-7]
