Answer 2

I can help you with your math problem. The expression 5у-10ху is a product of two binomials: (5+х)(у-х). You can use the formula for the difference of squares to simplify it: $$a^2-b^2=(a+b)(a-b)$$

In this case, $$a=5+х$$ and $$b=х$$, so $$a^2-b^2=(5+х)^2-х^2=(5+х+х)(5+х-х)=10(5+х)$$

Therefore, $$5у-10ху=(5+х)(у-х)=10(5+х)\frac{у-х}{10}=5(5+х)(у-х)$$
