Final Answer :
D
Explanation :
First, we can simplify the expression inside the first fraction by expanding the square:
(x−4y)2x+4y=x2−8xy+16y2x+4y\frac{(x-4y)^2}{x+4y}=\frac{x^2-8xy+16y^2}{x+4y}x+4y(x4y)2=x+4yx28xy+16y2
Then, we can simplify the expression inside the second fraction by factoring the quadratic:
x2+10xy+24y2x2−16y2=(x+6y)(x+4y)(x+4y)(x−4y)=x+6yx−4y\frac{x^2+10xy+24y^2}{x^2-16y^2}=\frac{(x+6y)(x+4y)}{(x+4y)(x-4y)}=\frac{x+6y}{x-4y}x216y2x2+10xy+24y2=(x+4y)(x4y)(x+6y)(x+4y)=x4yx+6y
Multiplying the two fractions, we get:
(x2−8xy+16y2)(x+6y)(x+4y)(x−4y)\frac{(x^2-8xy+16y^2)(x+6y)}{(x+4y)(x-4y)}(x+4y)(x4y)(x28xy+16y2)(x+6y)
We can further simplify by factoring the numerator:
(x−4y)(x−6y)(x+6y)(x+4y)(x−4y)\frac{(x-4y)(x-6y)(x+6y)}{(x+4y)(x-4y)}(x+4y)(x4y)(x4y)(x6y)(x+6y)
Canceling out the common factor of $x-4y$, we are left with:
(x−6y)(x+6y)x+4y\frac{(x-6y)(x+6y)}{x+4y}x+4y(x6y)(x+6y)
Therefore, the final answer is: D.
