Question

1)xy-y²=2)a²+5aв=3)15с-10с²=​

Answer 1

1) y(x-y)

2)a(a+5b)

3)5c(3-2c)

Answer 2

It seems that you have provided three equations without explicitly stating what you would like to do with them. However, I can help you solve or manipulate these equations based on your requirements.

1. $xy - y^2 = 2$

Let's analyze this equation. It's a nonlinear equation involving two variables, $x$ and $y$. To solve for $x$ or $y$, we need additional information or more equations.

2. $a^2 + 5ab = 3$

This is a quadratic equation in two variables, $a$ and $b$. If you want to solve for one variable in terms of the other, you'll need more information or equations.

3. $15c - 10c^2 = 0$

This is a quadratic equation in $c$. To solve for $c$, we can factor the equation:

$5c(3-2c) = 0$

So, the solutions are $c = 0$ and $c = \frac{3}{2}$.

If you have any specific requests or need me to perform a particular operation on these equations, please let me know, and I'll be glad to assist you further.
