Question

А) 11с во 2 - 11х во 2=???

Answer 1

будет

11 с во второй - 11х во второй = 11(с-х)*(с+х)

Answer 2

The expression you've provided is a quadratic equation. To simplify it, let's combine like terms:

11s^2 - 11x^2

Since the terms have a common factor of 11, we can factor it out:

11(s^2 - x^2)

Now, we have a difference of squares. This can be further factored as:

11(s + x)(s - x)

So, the simplified form of the expression 11s^2 - 11x^2 is 11(s + x)(s - x).
