Answer 2

Произведение = 0

Каждый множитель может быть нулем.

при (14у+28)=0

       14у=-28

          у=-2

при (1,8-0,3у)=0

        1,8=0,3у

         18=3у

          у=6

Ответ: -2; 6.

Answer 3

To solve the given equation $(14y + 28)(1.8 - 0.3y) = 0$, you need to find the values of $y$ that make the equation true. To do this, you can use the fact that the product of two factors is equal to zero if and only if at least one of the factors is equal to zero.

So, you can set each factor equal to zero and solve for $y$:

First factor: $14y + 28 = 0$ $14y = -28$ $y = -28/14$ $y = -2$

Second factor: $1.8 - 0.3y = 0$ $-0.3y = -1.8$ $y = -1.8 / -0.3$ $y = 6$

So, the solutions for $y$ that satisfy the equation $(14y + 28)(1.8 - 0.3y) = 0$ are $y = -2$ and $y = 6$.
