Algebra.Com's Answer #261916 by mananth(16949) You can put this solution on YOUR website! let the number be x \n" ); document.write( "its reciprocal = 1/x \n" ); document.write( "x= 1/x -7/12\r \n" ); document.write( "\n" ); document.write( "x-1/x = -7/12 \n" ); document.write( "x^2- 1 /x = -7/12 \n" ); document.write( "12(x^2-1)= -7x \n" ); document.write( "12x^2-12 = 7x \n" ); document.write( "12x^2+7x-12 =0 \n" ); document.write( "use quadratic equation to find the roots \n" ); document.write( "x1=(-7+sqrt(625))/24 \n" ); document.write( "x1= 0.75 \n" ); document.write( "x2=(-7-sqrt(625))/24 \n" ); document.write( "x2= -1.333 \n" ); document.write( ".. \n" ); document.write( "m.ananth@hotmail.ca \n" ); document.write( " |
