<span>To find the Median, place the numbers you are given in value order and find the middle number
</span>To find the range<span>, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.</span><span>

Given with a polynomial 4X² + 36/4X *1/5X, we can combine terms with the same power. First, let us perform multiplication of the 2nd and 3rd terms such as the given become 4X² + 36/20X². Then, we can reduce 36 and 20 by 4 and the result is 4X² + 9/5X². We can now proceed combining the terms since they have same power and result will be same as below:
(20X^4 + 9)/5X²
