Question

(...-...)(6x^2-5y^2)=12x^3+42x^2y-...-35y^3

Answer 1

... обозначим как a, b, c, тогда вот так (a-b)(6x^2-5y^2)=12x^3+42x^2y-c-35y^3.

6x^2*a = 12x^3, a = 2x

-b*(-5y^2) = 35y^3, b = -7y

Подставляем a и b влево, раскрываем скобки, получаем c = 10xy^2.

Answer 2

It seems like you have provided an equation and it got cut off in the middle. However, based on the given information, I can try to help you analyze it.

The equation you provided is:

(-...)(6x^2 - 5y^2) = 12x^3 + 42x^2y - ... - 35y^3

Since some terms are missing or represented as "...," it is challenging to provide a specific solution or simplification for this equation. If you can provide the complete equation or specify the missing terms, I'll be happy to assist you further.
