Algebra.Com's Answer #246383 by ewatrrr(24785) You can put this solution on YOUR website! So if x²=4x+12, SOLVE FOR X. \n" ); document.write( "Quadratic equation:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "which can be factored: \n" ); document.write( "(x-6)(x+2)=0 \n" ); document.write( "(x-6)=0 \n" ); document.write( "x=6 \n" ); document.write( " |
