\n" ); document.write( "let a positive number be $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( "if the square of a positive number is decrease by five times the number, the result is $\"14\"$ , then we have\r
\n" ); document.write( "\n" ); document.write( " $\"x%5E2-5x=14\"$ ....solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x%5E2-5x-14=0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x%5E2%2B2x-7x-14=0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%28x%5E2%2B2x%29-%287x%2B14%29=0\"$ \r

\n" ); document.write( "\n" ); document.write( " $\"x=7\"$
\n" ); document.write( "or
\n" ); document.write( " $\"x=-2\"$ -> since you need positive number, disregard negative solution\r
\n" ); document.write( "\n" ); document.write( "so, your number is $\"7\"$ \r
