Question

Сократите дробь 7x+7y/ x^2-y^2​

Answer 1

Объяснение:

(7х + 7у) / (х² - у²) =

= 7*(х + у) / (х - у)(х + у) = 7 / (х - у)

Answer 2

To simplify the given fraction (7x + 7y) / (x^2 - y^2), we first factor the denominator:

x^2 - y^2 = (x + y)(x - y)

Now, we can rewrite the fraction as:

(7x + 7y) / (x^2 - y^2) = 7(x + y) / ((x + y)(x - y))

Next, we can cancel out the common factor of (x + y) in the numerator and denominator:

(7x + 7y) / (x^2 - y^2) = 7 / (x - y)

So, the simplified form of the fraction is 7 / (x - y).
