To solve this problem you can apply the proccedure shown below:
1. You have the fexpression given in the problem above, which you can rewrite it as following:
-4√(9/2x)
2. You can find an equivalent expression:
-4√(3²/2x)
(-4)(3)√(1/2x)
-12/√2x
3- If you multiply the numerator and the denominator by √2, you obtain:
(-12√2)/[(√2)²√x]
(-12√2)/(2√x)
(-6√2)/(√x)
Therefore, the answer is:-(-6√2)/(√x)
