The cell membrane consists of a phospholipid bilayer. Phospholipids are molecules with a hydrophilic (water loving) tail. And a hydrophobic (water repelling) tail. The cell environme...

by completing the square we write the equation as (x+b/2)^2-b/2^2+c, in this case b=8 (the coefficient of x) and c=5 so we have (x+4)^2-16-5=0, which equals (x+4)^2-21=0. Now by rearranging we get (x+4)^2...
