We are having trouble factoring on this problem:
\n" ); document.write( "12y^2-24y-72\r
\n" ); document.write( "\n" ); document.write( "= 12(y^2-2y-6)\r
\n" ); document.write( "\n" ); document.write( "Factoring y^2-2y-6 with the quadratic formula:
\n" ); document.write( "y = [2 +- sqrt(4 -4*1*-6)]/2
\n" ); document.write( "y = [2 +- sqrt(28)]/2
\n" ); document.write( "y = [1 +- sqrt7]
\n" ); document.write( "Factors are 12, (y-(1+sqrt7)), (y-(1-sqrt(7))
\n" ); document.write( "===========================
