5x^2 becomes 25x as the 2 comes down and 2x becomes 2 as x becomes 1.dy/dx = 25x + 2=10x+2

Firstly, let's start off with the simplest type of bonding. Ionic bonding involves the transfer of electrons, usually from a metal (Sodium/Na) to a non-metal (Chlorine, Cl). This creates an attraction bet...
