Question

1 дробь а в квадрате плюс а-2 дробь а. Помогите решить!

Answer 1

1/(a² +a) -2/a =1/a(a +1) -2/a =

=(1 -2(a+1)) /a(a+1) =(1 -2a -1) /a(a+1) =

= -2a /a(a+1) = -2 /(a+1)

Answer 2

Solving the Equation

To solve the equation 1/a + a^2 + a - 2/a, we can follow these steps:

1. Identify the Equation: The given equation is 1/a + a^2 + a - 2/a. 2. Combine Like Terms: Combine the terms with the same variable. 3. Simplify the Equation: Simplify the equation to solve for the variable.

Step-by-Step Solution

1. Identify the Equation: - The given equation is 1/a + a^2 + a - 2/a.

2. Combine Like Terms: - Combine the terms with the same variable: - 1/a - 2/a + a^2 + a - (1 - 2)/a + a^2 + a - -1/a + a^2 + a

3. Simplify the Equation: - The equation -1/a + a^2 + a is the simplified form of the given equation.

So, the simplified form of the equation 1/a + a^2 + a - 2/a is -1/a + a^2 + a.

This is the solution for the given equation.
