12/(x^2+x-12) - 1/(x-3) = -1
\n" ); document.write( "---
\n" ); document.write( "Factor:
\n" ); document.write( "12/[(x+4)(x-3)] - 1/(x-3) = -1
\n" ); document.write( "---
\n" ); document.write( "Multiply thru by (x+4)(x-3) to get:
\n" ); document.write( "12 - (x+4) = -(x^2+x-12)
\n" ); document.write( "12 -x -4 = -x^2 -x + 12
\n" ); document.write( "x^2 -4 = 0
\n" ); document.write( "x = 2 or x = -2
