Question

Y² - 10y + 25 - 3xy +15x

Answer 1

у^2 - 10у+25-3ху+15х= (у^2-10у+25) -(3ху-15х) =(у-5)^2 - 3х×(у-5) =(у-5) ×(у-5-3х)

Answer 2

The expression you've given is a polynomial with two variables, y and x:

Y² - 10y + 25 - 3xy + 15x

To simplify or factor this expression, we can do the following:

1. Factor by grouping (if possible):

   Y² - 10y + 25 - 3xy + 15x

   You can group the terms as follows:

   (Y² - 10y + 25) - (3xy - 15x)

2. Factor each group:

   Group 1: Y² - 10y + 25 can be factored as (Y - 5)(Y - 5) or (Y - 5)².

   Group 2: 3xy - 15x can be factored as 3x(y - 5).

3. Combine the factored groups:

   (Y - 5)² - 3x(y - 5)

So, the simplified expression is:

(Y - 5)² - 3x(y - 5)

This is the factored form of the given expression.
