Algebra.Com's Answer #331359 by ankor@dixie-net.com(22740) You can put this solution on YOUR website! Let x = \"the number\" \n" ); document.write( ": \n" ); document.write( "twice the reciprocal of a certain number when added to 3 is equal to the number with its sign is changed. \n" ); document.write( "2( \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( "multiply both sides by x \n" ); document.write( "2 + 3x = -x^2 \n" ); document.write( "A quadratic equation \n" ); document.write( "x^2 + 3x + 2 = 0 \n" ); document.write( "Factors to \n" ); document.write( "(x+2)(x+1) = 0 \n" ); document.write( "two solutions \n" ); document.write( "x = -2 \n" ); document.write( "x = -1 \n" ); document.write( "Check both solution in the original statement \n" ); document.write( " |
