Question

(x-0,5)(7+x)=0 решите!!

Answer 1

(x - 1/2)(7+x)=0
x - 1/2 = 0
7+x = 0

x1 = 1/2
x2 = -7




x1 и x2 это все возможные случаи

Answer 2

To solve the equation $(x-0.5)(7+x) = 0$, we need to find the values of $x$ that make the equation true. When the product of two factors is equal to zero, one or both of the factors must be zero. So, we set each factor to zero and solve for $x$:

1. $x - 0.5 = 0$ Add 0.5 to both sides to isolate $x$: $x = 0.5$

2. $7 + x = 0$ Subtract 7 from both sides to isolate $x$: $x = -7$

So, the solutions to the equation are $x = 0.5$ and $x = -7$.
