Algebra.Com's Answer #79831 by stanbon(75887) ![]() You can put this solution on YOUR website! Solve using the quadratic formula: \n" ); document.write( "x2 – 3x = 7x – 2 \n" ); document.write( "x^2-10x+2 = 0 \n" ); document.write( "x = [10 +- sqrt(100-4*2)]/2 \n" ); document.write( "x = [10 +- sqrt(92)]/2 \n" ); document.write( "x = [10 +- 2sqrt(23)]/2 \n" ); document.write( "x = 5 + sqrt23 or x = 5 - sqrt23 \n" ); document.write( "============== \r \n" ); document.write( "\n" ); document.write( "x2 – 7x – 1 = -7 \n" ); document.write( "x^2-7x+6 = 0 \n" ); document.write( "x = [7 +- sqrt(49-4*6)]/2 \n" ); document.write( "x = [7 +- sqrt(25)]/2 \n" ); document.write( "x = [7 +- 5]/2 \n" ); document.write( "x = 6 or x = 1 \n" ); document.write( "================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
