Algebra.Com's Answer #284853 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The equation x^2 + k = 6 x has two distinct real roots. Find the range of values of k. \n" ); document.write( "--- \n" ); document.write( "Ans: 2 distict Real roots implies b^2-4ac > 0 \n" ); document.write( "---- \n" ); document.write( "Rearrange the equation: \n" ); document.write( "x^2-6x+k = 0 \n" ); document.write( "Solve:; 6^2-4*1*k > 0 \n" ); document.write( "36 -4k > 0 \n" ); document.write( "36 > 4k \n" ); document.write( "k < 9 \n" ); document.write( "That is the range of the values of \"k\". \n" ); document.write( "---------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
