Algebra.Com's Answer #500677 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! Look at the lesson linked through my profile, \"Completing the Square to Solve General Quadratic Equation\". You will want to change goal a little bit and put the equation into standard form, from which you can read the vertex point coordinates. The x-intercepts are the general solutions to a quadratic formula. For y-intercept, just let x=0, which you can do with the general form equation which you are given.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "------ \n" ); document.write( "x intercepts: \n" ); document.write( " \n" ); document.write( "just compute the two values. \n" ); document.write( " |
