Find the area of each figure.
You can factor out 36*5=180 and 27*4=108 and find that they have 36 as greatest common divisor. The x and y factors have xy as the best you can divide by. So the factor becomes 36xy
36xy(5y²+3) = 36x5y³ + 27x4y
F(X) = x^4 +64x^2
x^4 +64x^2 = x^2(x^2 +64)
hope this will help you
