Solving the Equation (x+2)^2*(x-7)*(x+5) = 0
This equation is a polynomial equation and we can solve it by finding the values of x that make the equation true.
Understanding the Equation
- The equation is set to zero. This means we are looking for the points where the expression on the left-hand side equals zero.
- The expression is a product of four factors: (x+2)^2, (x-7), and (x+5).
The Zero Product Property
The key to solving this equation is the Zero Product Property: If the product of two or more factors is zero, then at least one of the factors must be zero.
Solving for x
To find the solutions, we set each factor equal to zero and solve for x:
-
(x+2)^2 = 0
- Take the square root of both sides: x + 2 = 0
- Solve for x: x = -2
-
(x-7) = 0
- Solve for x: x = 7
-
(x+5) = 0
- Solve for x: x = -5
The Solutions
Therefore, the solutions to the equation (x+2)^2*(x-7)*(x+5) = 0 are:
- x = -2 (This solution has a multiplicity of 2 because the factor (x+2) appears squared.)
- x = 7
- x = -5
Conclusion
The equation (x+2)^2*(x-7)*(x+5) = 0 has three solutions: x = -2, x = 7, and x = -5. These are the values of x that make the expression on the left-hand side equal to zero.
