When the sum of 514 and three times a positive number is subtracted from the square of the number, the result is 84. Find the number.
\n" ); document.write( "**
\n" ); document.write( "let x=the positive number
\n" ); document.write( "x^2-(514+3x)=84
\n" ); document.write( "x^2-514-3x=84
\n" ); document.write( "x^2-3x-598=0
\n" ); document.write( "factor or solve by quadratic formula
\n" ); document.write( "(x+23)(x-26)=0
\n" ); document.write( "x=-23(reject)
\n" ); document.write( "or
\n" ); document.write( "x=26
\n" ); document.write( "number=26 \n" ); document.write( "
