Solving the Equation: (x-4)(x-6)-(x-2)(x+2)=-2
This article will guide you through the process of solving the equation (x-4)(x-6)-(x-2)(x+2)=-2. We will break down each step to make it easy to understand.
Expanding the Equation
First, we need to expand the equation by multiplying the terms in the parentheses:
- (x-4)(x-6) = x² - 6x - 4x + 24 = x² - 10x + 24
- (x-2)(x+2) = x² + 2x - 2x - 4 = x² - 4
Now our equation becomes: x² - 10x + 24 - (x² - 4) = -2
Simplifying the Equation
Next, we simplify the equation by combining like terms:
- x² - x² = 0
- -10x remains as -10x
- 24 + 4 = 28
- So the equation becomes: -10x + 28 = -2
Isolating the Variable (x)
Now, we need to isolate the variable 'x' by moving the constant term (28) to the right side of the equation:
- -10x = -2 - 28
- -10x = -30
Solving for x
Finally, we solve for 'x' by dividing both sides of the equation by -10:
- x = -30 / -10
- x = 3
Conclusion
Therefore, the solution to the equation (x-4)(x-6)-(x-2)(x+2)=-2 is x = 3.
