Inequations

Solution

The expression in the image is:

(2x4)(x+3)x2\frac{(2x - 4)(x + 3)}{x - 2}

To analyze this expression, let's look at each component:

  1. Numerator: (2x4)(x+3)(2x - 4)(x + 3)
  2. Denominator: x2x - 2

Step-by-Step Solution

  1. Identify the values that make the expression undefined:

    • The denominator x2=0x - 2 = 0 when x=2x = 2. So, the expression is undefined at x=2x = 2.
  2. Simplify the expression:

    • Notice that 2x42x - 4 can be factored as 2(x2)2(x - 2).

Thus, the expression becomes:

2(x2)(x+3)x2\frac{2(x - 2)(x + 3)}{x - 2}

  1. Cancel common factors:
    • We can cancel x2x - 2 in the numerator and denominator (except where x=2x = 2, as the original expression is undefined there):

2(x+3)2(x + 3)

So, the simplified expression is:

2(x+3)2(x + 3)

Note: The simplified expression is valid for all xx except x=2x = 2.

Conclusion

The simplified form of the given algebraic expression is 2(x+3)2(x + 3), with the condition that x2x \neq 2.
