# Thread: Simplify the below equation

1. ## Simplify the below equation

(k-4)/(K^2+5K+6) * (k^2+8K+12)/(K^2-10K+24)

2. You can factor all those expressions to make life simpler

$\dfrac{(k-4)}{(k+3)(k+2)} \cdot \dfrac{(k+6)(k+2)}{(k-6)(k-4)}$

As long as $k \neq -2, -3, 4, 6$ you can do some cancelling

3. Deleted by repetition.

4. That is not an equation but a rational fraction. To simplify, decompose the second degree polynomials, for example $k^2-10k+24=(k-4)(k-6)$ .
