Algebra.Com's Answer #138121 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Just write an equation for what it says: \n" ); document.write( "seven more then 11 times a number is 6 times the square of the number \n" ); document.write( "11x + 7 = 6x^2 \n" ); document.write( ": \n" ); document.write( "0 = 6x^2 - 11x - 7; our old friend, the quadratic equation! \n" ); document.write( ": \n" ); document.write( "Unless they're trying to torment us, it should factor. \n" ); document.write( "(2x + 1) (3x - 7) = 0 \n" ); document.write( "Two solutions \n" ); document.write( "2x = -1 \n" ); document.write( "x = \n" ); document.write( "and \n" ); document.write( "3x = +7 \n" ); document.write( "x = \n" ); document.write( "x = 2 \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check the 1st solution using x = -.5 in the original statement: \n" ); document.write( "\"seven more then 11 times a number is 6 times the square of the number\" \n" ); document.write( "11(-.5) + 7 = 6(-.5)^2 \n" ); document.write( "-5.5 + 7 = 6(.25) \n" ); document.write( "+1.5 = +1.5 \n" ); document.write( ": \n" ); document.write( "You can check the the x = \n" ); document.write( " \n" ); document.write( " |
