\n" ); document.write( "A square has an area of 16x^2+56x+49. Find the length of the side.

16x^2+56x+49 sub into \"%28a%2Bb%29%5E2=a%5E2%2B2ab%2Bb%5E2\"
\n" ); document.write( "(4x)^2+(2)*(4)*(7)+(7)^2
\n" ); document.write( "=(4x+7)^2\r
\n" ); document.write( "\n" ); document.write( "So therefore the square is (4x+7)*(4x+7). So therefore one side of the square is 4x+7.
\n" ); document.write( "I'll try to make a sketch. (dots are filler)
\n" ); document.write( "...
\n" ); document.write( "....4x + 7
\n" ); document.write( ". . ____ ____
\n" ); document.write( "4x[16x^2[..28x..[
\n" ); document.write( ". .[____[____[
\n" ); document.write( ". .[ ..28x..[ ..49..[
\n" ); document.write( "+7[____[____[\r
\n" ); document.write( "\n" ); document.write( "Does that make sense?
\n" ); document.write( "That is supposed to be a square, divided into four sections.
\n" ); document.write( "Both sides are 4x+7.
\n" ); document.write( "If you add up the area inside, you'll get what was in the question. I got the area in the subdivisions by l*w. 4x*4x=16x^2 ... 4x*7=28 ... 7*7=49\r
