You can put this solution on YOUR website!
A square has an area of 16x^2+56x+49.
\n" ); document.write( "I think this should be 16x^2-56x+49, otherwise you get a neg solution
\n" ); document.write( ":
\n" ); document.write( " Find the length of the side.
\n" ); document.write( ":
\n" ); document.write( "Note that in this expression, the 16 and 49 are perfect squares, 4^2 & -7^2
\n" ); document.write( "the coefficient of x is the sum of (4*-7)+(4*-7) therefore
\n" ); document.write( "This can be factored as a perfect square
\n" ); document.write( "(4x-7)(4x-7) = 0
\n" ); document.write( "4x = 7
\n" ); document.write( "x = \"7%2F4\"
\n" ); document.write( "x = 1.75 units, the side of the square
\n" ); document.write( "
\n" );
