Solving the Equation: (x-2)(x+3)-(x+4)(x-7)=5-x
This article will guide you through solving the algebraic equation: (x-2)(x+3)-(x+4)(x-7)=5-x. We will break down the steps involved in finding the solution for 'x'.
1. Expanding the Equation
First, we need to expand the equation by multiplying the terms in the brackets.
- (x-2)(x+3): This expands to x² + x - 6
- (x+4)(x-7): This expands to x² - 3x - 28
Now, the equation becomes: x² + x - 6 - (x² - 3x - 28) = 5 - x
2. Simplifying the Equation
Next, we simplify the equation by removing the parentheses and combining like terms:
- x² + x - 6 - x² + 3x + 28 = 5 - x
- 4x + 22 = 5 - x
3. Isolating 'x'
To isolate 'x' on one side of the equation, we need to move all the 'x' terms to one side and the constant terms to the other side.
- 4x + x = 5 - 22
- 5x = -17
4. Solving for 'x'
Finally, we solve for 'x' by dividing both sides of the equation by 5:
- x = -17/5
Therefore, the solution to the equation (x-2)(x+3)-(x+4)(x-7)=5-x is x = -17/5.
