You must know that : (a-b) ^2 = a^2 - 2ab + b^2 so let a=x and b=2, applying above formula you'll get f(x) = x^2 - 4x +4 + 4 =x^2 - 4x +8 Hope you got it ;-) Revert back if you still face any trouble.
From the data you gave us
Median: 2
Mean: 2

Answer:
The height of cylinder is 9 cm
Step-by-step explanation:
Volume of cylinder = 198 cm³
Base Area = 22 cm²
We need to find height of the cylinder
The formula used is:
Where
First we need to find radius r
So, we get radius r = 2.656
Putting values of volume and radius are to find height
So, the height of cylinder is 9 cm
