2-(x-2)(x-3)%3D1.jpeg "(x2-5x+7)2-(x-2)(x-3)=1")
Solving the Equation: (x²-5x+7)² - (x-2)(x-3) = 1
This problem involves simplifying and solving a quadratic equation. Let's break it down step by step:
Step 1: Expanding the Equation
First, we need to expand the equation by performing the multiplications:
- (x²-5x+7)²: This is a square of a trinomial. We can use the formula (a + b + c)² = a² + b² + c² + 2ab + 2ac + 2bc to expand it.
- (x-2)(x-3): This is a simple multiplication of two binomials. We can use the FOIL method (First, Outer, Inner, Last) to expand it.
Expanding the equation, we get:
(x⁴ - 10x³ + 39x² - 70x + 49) - (x² - 5x + 6) = 1
Step 2: Simplifying the Equation
Now, we simplify the equation by combining like terms:
x⁴ - 10x³ + 38x² - 65x + 43 = 1
Step 3: Rearranging the Equation
We need to set the equation equal to zero to solve for x:
x⁴ - 10x³ + 38x² - 65x + 42 = 0
Step 4: Factoring the Equation
This is a fourth-degree polynomial, and factoring it directly can be challenging. We can try to factor it by grouping or using the Rational Root Theorem. However, in this case, it might be easier to use a numerical method like the quadratic formula or graphing to find the solutions.
Step 5: Solving for x
Using a numerical method like the quadratic formula or graphing, we can find the solutions for x. This will give us the values of x that satisfy the original equation.
Note: The process of solving this equation might involve complex numbers.
By following these steps, we can successfully solve the equation and find the values of x that make the equation true.
