Solving the Equation (x+2)(x-3) = (x-5)(x-6)
This article will guide you through the steps of solving the equation (x+2)(x-3) = (x-5)(x-6).
Expanding the Equation
First, we need to expand both sides of the equation by multiplying the factors:
- Left side: (x+2)(x-3) = x² - x - 6
- Right side: (x-5)(x-6) = x² - 11x + 30
Now our equation looks like this: x² - x - 6 = x² - 11x + 30
Simplifying the Equation
Next, let's simplify the equation by combining like terms. We can subtract x² from both sides, which cancels out the x² terms:
- -x - 6 = -11x + 30
Now let's isolate the x terms by adding 11x to both sides:
- 10x - 6 = 30
Finally, add 6 to both sides to isolate the x term:
- 10x = 36
Solving for x
To solve for x, we divide both sides by 10:
- x = 36/10
Simplifying the fraction, we get:
- x = 18/5
Checking the Solution
To ensure our solution is correct, we can plug x = 18/5 back into the original equation:
- (18/5 + 2)(18/5 - 3) = (18/5 - 5)(18/5 - 6)
Simplifying both sides:
-
(28/5)(3/5) = (-7/5)(-12/5)
-
84/25 = 84/25
Since both sides of the equation are equal, we can confirm that x = 18/5 is the correct solution.
Conclusion
By expanding, simplifying, and solving the equation, we have found that the solution for (x+2)(x-3) = (x-5)(x-6) is x = 18/5. Remember to always check your solution by plugging it back into the original equation to ensure its validity.
