Solving the Equation (4x-5)^2 - (2x+3)^2 = 0
This equation involves the difference of squares, which can be factored to simplify the process. Here's how to solve it:
Factoring the Equation
-
Recognize the Difference of Squares: The equation is in the form of a² - b² = 0, where a = (4x - 5) and b = (2x + 3).
-
Apply the Difference of Squares Formula: The difference of squares formula states that a² - b² = (a + b)(a - b). Applying this to our equation:
[(4x - 5) + (2x + 3)][(4x - 5) - (2x + 3)] = 0
-
Simplify the Expression:
(6x - 2)(2x - 8) = 0
Solving for x
Now we have a product of two factors that equals zero. For this to be true, at least one of the factors must be equal to zero.
-
Set each factor to zero:
- 6x - 2 = 0
- 2x - 8 = 0
-
Solve for x in each equation:
- 6x = 2 => x = 1/3
- 2x = 8 => x = 4
Solution
Therefore, the solutions to the equation (4x - 5)² - (2x + 3)² = 0 are x = 1/3 and x = 4.
