If so... Area Garden = (x+4)(x+4) FOIL -> x^2+4x+4x+16 = x^2+8x+16 Area Shed = (3x)(3x) = 9x^2 Area Garden - Area Shed= -8x^2+8x+16 or -8(x^2-x-2) I think.

Area Garden = (x+4)(x+4)
FOIL -> x^2+4x+4x+16 = x^2+8x+16
Area Shed = (3x)(3x) = 9x^2
Area Garden – Area Shed= -8x^2+8x+16
or -8(x^2-x-2)
I think.
