Algebra.Com's Answer #378806 by w_parminder(53)![]() ![]() You can put this solution on YOUR website! 3x^2-14x-24 is a polynomial\r \n" ); document.write( "\n" ); document.write( "but \n" ); document.write( "3x^2-14x-24=0 is an equation\r \n" ); document.write( "\n" ); document.write( "comparing this with general quadratic equation ax^2+bx+c=0 we get \n" ); document.write( "a=3, b=-14, c=-24\r \n" ); document.write( "\n" ); document.write( "you can now solve it by using the formula but I prefer to use 'spliting the middle term' method\r \n" ); document.write( "\n" ); document.write( "using this method, the given equation can be written as \n" ); document.write( " \n" ); document.write( "3x can be taken out as common from first two terms and 4 from the last two,so the equation becomes \n" ); document.write( " \n" ); document.write( "taking (x-6) common from the two terms,we get \n" ); document.write( "(x-6)(3x+4)=0 \n" ); document.write( "Now either (x-6)=0, OR (3x+4)=0\r \n" ); document.write( "\n" ); document.write( "solving these equations, \n" ); document.write( "either x=6 OR x=-4/3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "for more info, and suggestions please contact me at vickywalias@gmail.com \n" ); document.write( " |
