Answer:
See below.
Step-by-step explanation:
So we have the expression:
![4u^4+4u^3-6u^2](https://tex.z-dn.net/?f=4u%5E4%2B4u%5E3-6u%5E2)
First, factor out the GCF.
The GCF is 2u². Thus:
![=2u^2(2u^2+2u-3)](https://tex.z-dn.net/?f=%3D2u%5E2%282u%5E2%2B2u-3%29)
And this is the simplest it can get.
So we are done :)

Answer:
Overall percent change of stock is increase by 16.3%
Step-by-step explanation:
Given:
A stock increases in value by 55%
Then the value decreases by 25%
To find the overall percent change of the stock.
Solution:
Let the initial value of the stock be = $100
Increase in value by 55% will be = ![0.55\times \$100=\$55](https://tex.z-dn.net/?f=0.55%5Ctimes%20%5C%24100%3D%5C%2455)
The new value after increase = ![\$100+\$55=\$155](https://tex.z-dn.net/?f=%5C%24100%2B%5C%2455%3D%5C%24155)
Decrease in value of 25% will be = ![0.25\times \$155=\$38.75](https://tex.z-dn.net/?f=0.25%5Ctimes%20%5C%24155%3D%5C%2438.75)
New value after decrease = ![\$155-\$38.75= \$116.25](https://tex.z-dn.net/?f=%5C%24155-%5C%2438.75%3D%20%5C%24116.25)
Overall change in value = ![\$116.25-\$100=\$16.25](https://tex.z-dn.net/?f=%5C%24116.25-%5C%24100%3D%5C%2416.25)
The over all percent change can be given as:
⇒ ![\frac{Change\ in\ value}{Original\ value}\times 100](https://tex.z-dn.net/?f=%5Cfrac%7BChange%5C%20in%5C%20value%7D%7BOriginal%5C%20value%7D%5Ctimes%20100)
⇒ ![\frac{\$16.25}{\$100}\times 100](https://tex.z-dn.net/?f=%5Cfrac%7B%5C%2416.25%7D%7B%5C%24100%7D%5Ctimes%20100)
⇒ ![16.25\%\approx 16.3\%](https://tex.z-dn.net/?f=16.25%5C%25%5Capprox%2016.3%5C%25)
Overall percent change of stock is increase by 16.3%
