Algebra.Com's Answer #138490 by J2R2R(94) You can put this solution on YOUR website! 2x^2 - x - 3 = (2x - 3)(x + 1) which must equal 0 on the x-axis.\r \n" ); document.write( "\n" ); document.write( "So, either 2x – 3 = 0 gives x = 1.5 or x + 1 = 0 gives x= -1.\r \n" ); document.write( "\n" ); document.write( "Therefore the intercepts of the x-axis where y = 0 is where x = -1 and x = 1.5 \n" ); document.write( " \n" ); document.write( " |
