If the sides of a square are increased by 3 inches, the area becomes 64 square inches. Find the length of the sides of the original square.
\n" ); document.write( "one square is x and the other is x+3
\n" ); document.write( ":
\n" ); document.write( "(x+3)*(x+3) = 64
\n" ); document.write( "FOIL
\n" ); document.write( "x^2 + 6x + 9 = 64
\n" ); document.write( ":
\n" ); document.write( "x^2 + 6x + 9 - 64 = 0
\n" ); document.write( ":
\n" ); document.write( "x^2 + 6x - 55 = 0
\n" ); document.write( "Factor
\n" ); document.write( "(x+11)(x-5) = 0
\n" ); document.write( "Positive solution
\n" ); document.write( "x = 5 inches side of original square
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check (5 + 3)^2 = 64 \n" ); document.write( "
\n" );
