I'm having trouble with quadratic equations; here is a problem that I cannot seem to solve: 9x^2+9x+2=0
\n" ); document.write( "Note: I put a \"+\" in place of the \"=\".
\n" ); document.write( "---------------
\n" ); document.write( "Use the quadratic formula to get:
\n" ); document.write( "x = [-9 +- sqrt(81-4*9*2)]/[2*9]\r
\n" ); document.write( "\n" ); document.write( "x = [-9 +- sqrt(9)]/18\r
\n" ); document.write( "\n" ); document.write( "x = [-9 +- 3] /18\r
\n" ); document.write( "\n" ); document.write( "x = -12/18 or x = -6/18
\n" ); document.write( "x = -2/3 or x = -1/3
\n" ); document.write( "-----------------------
\n" ); document.write( "Using factoring:
\n" ); document.write( "9x^2+9x+2=0
\n" ); document.write( "9x^2 + 3x + 6x + 2 = 0
\n" ); document.write( "3x(3x+1) + 2(3x+1) = 0
\n" ); document.write( "(3x+1)(3x+2) = 0
\n" ); document.write( "x = -1/3 or x = -2/3
\n" ); document.write( "==========================
