Solving the Equation (x+3)(x+5)/(x+2) = 0
This equation presents a common scenario in algebra where we need to find the values of 'x' that make the equation true. Let's break down the steps involved in solving it:
Understanding the Equation
The equation (x+3)(x+5)/(x+2) = 0 involves a rational expression. A rational expression is a fraction where the numerator and denominator are polynomials. To solve this type of equation, we need to consider the following:
- Zero Product Property: This property states that if the product of two or more factors is zero, then at least one of the factors must be zero.
- Undefined Values: A rational expression is undefined when the denominator is zero. We need to exclude any values of 'x' that make the denominator zero.
Solving the Equation
-
Find the values that make the numerator zero:
- Set the numerator equal to zero: (x+3)(x+5) = 0
- Apply the zero product property:
- x + 3 = 0 => x = -3
- x + 5 = 0 => x = -5
-
Find the values that make the denominator zero:
- Set the denominator equal to zero: x + 2 = 0
- Solve for 'x': x = -2
-
Exclude the undefined value:
- Since the denominator cannot be zero, we exclude the value x = -2 from the possible solutions.
-
Check for extraneous solutions:
- We need to check if the solutions we found, x = -3 and x = -5, actually satisfy the original equation. In this case, both values work because they do not make the denominator zero.
Conclusion
Therefore, the solutions to the equation (x+3)(x+5)/(x+2) = 0 are x = -3 and x = -5. Remember to always consider the zero product property and undefined values when solving rational equations.
