Lw = 70
\n" ); document.write( "L = 2w + 4
\n" ); document.write( "---
\n" ); document.write( "Lw = 70
\n" ); document.write( "(2w + 4)w = 70
\n" ); document.write( "2ww + 4w - 70 = 0
\n" ); document.write( "---
\n" ); document.write( "the above quadratic equation is in standard form, with a=2, b=4, and c=-70
\n" ); document.write( "---
\n" ); document.write( "to solve the quadratic equation, by using the quadratic formula, plug this:
\n" ); document.write( "2 4 -70

\n" ); document.write( "the two real roots (i.e. the two x-intercepts), of the quadratic are:
\n" ); document.write( "w = 5
\n" ); document.write( "w = -7
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "w = 5 ft
\n" ); document.write( "L = 14 ft
