Algebra.Com's Answer #671422 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! The square of a negative number is 35 more than 2 times the negative number. \n" ); document.write( " Find the number. \n" ); document.write( "let n = the number \n" ); document.write( "n^2 = 2(n) + 35 \n" ); document.write( "n^2 = 2n + 35 \n" ); document.write( "arrange as a quadratic equation \n" ); document.write( "n^2 - 2n - 35 = 0 \n" ); document.write( "Factors to \n" ); document.write( "(n-7)(n+5) = 0 \n" ); document.write( "they want the negative solution \n" ); document.write( "n = -5 \n" ); document.write( ": \n" ); document.write( "; \n" ); document.write( "See if that works \n" ); document.write( "(-5)^2 = 2(-5) + 35 \n" ); document.write( "25 = -10 + 35 \n" ); document.write( " \n" ); document.write( " |
