Answer:

\dfrac{z-y}{a+b}

Step-by-step explanation:

Given expression:

\dfrac{z^2-y^2}{a^2-b^2}\div \dfrac{z+y}{a-b}

Substitute

a^2-b^2=(a-b)(a+b)\\ \\z^2-y^2=(z-y)(z+y)

into the expression:

\dfrac{(z-y)(z+y)}{(a-b)(a+b)}\div \dfrac{z+y}{a-b}\\ \\ \\=\dfrac{(z-y)(z+y)}{(a-b)(a+b)}\times \dfrac{a-b}{z+y}\\ \\ \\=\dfrac{z-y}{a+b}
