Question

Б)(х+3/7)×(х-0,8)=0 ​

Answer 1

(x+3/7)(x-0,8)=0

x+3/7=0 или x-0,8=0

x=0-3/7 или x=0+0,8

x=-3/7 или x=0,8

Ответ:x=-3/7;x=0,8

Answer 2

To solve the equation $(x + \frac{3}{7}) \times (x - 0.8) = 0$, we need to find the values of $x$ that make the equation true. The equation is already factored, so we can set each factor to zero and solve for $x$.

Step 1: Set each factor to zero:

1. $x + \frac{3}{7} = 0$
2. $x - 0.8 = 0$

Step 2: Solve for $x$ in each equation:

1. $x = -\frac{3}{7}$
2. $x = 0.8$

These are the solutions for the equation. So, the two values of $x$ that satisfy the equation are $x = -\frac{3}{7}$ and $x = 0.8$.
