Question

Упростить выражение:(y-10)(y-2)+(y+4)(y-5)

Answer 1

(y-10)(y-2)+(y+4)(y-5)= y^2-2y-10y+20+y^2-5y+4y-20=2y^2-13y

Answer 2

I can chat with you in Russian. To simplify the expression, we need to use the distributive property and combine like terms. Here are the steps:

- First, we multiply each term in the first parentheses by each term in the second parentheses. This gives us:

$$ (y-10)(y-2) + (y+4)(y-5) = y^2 - 12y + 20 + y^2 - y - 20 $$

- Next, we combine the like terms, which are the terms that have the same variable and exponent. This gives us:

$$ y^2 - 12y + 20 + y^2 - y - 20 = 2y^2 - 13y $$

- Finally, we check if we can factor the expression further. Since there are no common factors for both terms, we cannot factor it further. Therefore, the simplified expression is:

$$ 2y^2 - 13y $$

I hope this helps you understand how to simplify expressions. If you have any other questions, feel free to ask me.Ответь+подробно.+Упростить+выражение:(y-10)(y-2)+(y+4)(y-5)
