You can put this solution on YOUR website!
(xy^7)(x^4y)/(x^5y^2)
\n" ); document.write( "when multiplying add exponents; when dividing subtract them.
\n" ); document.write( "=(x^5y^11)/(x^5y^2)
\n" ); document.write( "=y^9
\n" ); document.write( ".
\n" ); document.write( "x-3/ x^2+7x+12
\n" ); document.write( "=(x-3)/(x+3)(x+4)
\n" ); document.write( ".
\n" ); document.write( "x^2-5x-1=0
\n" ); document.write( "x^2-5x =1
\n" ); document.write( "x^2-5x+6.25=6.25+1 Complete the square.
\n" ); document.write( "(x-2.5)^2=7.25
\n" ); document.write( "x-2.5=+-sqrt(7.25) sqrt of each side
\n" ); document.write( "x=2.5+sqrt(7.25), x=2.5-sqrt(7.25)
