Ответ:
x = 0 and x = -2 are solutions of the given rational equation.
Step-by-step explanation:
We must solve the following rational equation:
Now we present the procedure:
1)
Given
2)
Compatibility with multiplication/Existence of the multiplicative inverse/Definition of division/Modulative property.
3)
Distributive property/![a^{b}\cdot a^{c} = a^{b+c}](/tpl/images/0793/4020/17064.png)
4)
Compatibility with addition/Existence of the additive inverse/Modulative property/Reflexive property
5)
Distributive property/![a^{b}\cdot a^{c} = a^{b+c}](/tpl/images/0793/4020/17064.png)
6)
Result
Now we check the rational equation with each root:
x = 0
x = 0 is a solution of the rational equation.
x = -2
x = -2 is a solution of the rational equation.
