x-5=0
x+2/5=0
ответ:
x1=0
x2=5
x3=-2/5

Answer 2

I can help you solve the equation $x(x-5)(x+2.5)=0$ in Russian. To solve this equation, you need to find the values of $x$ that make the expression equal to zero. You can use the zero product property, which states that if $ab=0$, then either $a=0$ or $b=0$ or both. In this case, you have three factors: $x$, $x-5$, and $x+2.5$. So you can set each factor equal to zero and solve for $x$:

$x=0$

$x-5=0 \implies x=5$

$x+2.5=0 \implies x=-2.5$

These are the three solutions of the equation. You can check them by plugging them back into the original equation and verifying that they make it equal to zero. For example, if $x=0$, then $0(0-5)(0+2.5)=0(0)(2.5)=0$. You can do the same for the other two values of $x$.

If you need more help with solving equations, you can use online calculators such as [Symbolab](https://ru.symbolab.com/solver/equation-calculator) or [Microsoft Math Solver](https://mathsolver.microsoft.com/ru/algebra-calculator). They can show you the steps and explanations for different types of equations. You can also learn more about the zero product property and other algebraic concepts from websites such as [Mathway](https://www.mathway.com/ru/Algebra). I hope this was helpful. Have a nice day!
