Case 1:
The factors of Q(x) are all linear and none is repeated. That is,
Q(x) = (x - a1 )(x - a 2 )
(x - a n )
where no two of the a i are identical. In this case, we write
P(x) A1 A2 = + + Q(x) x - a1 x - a 2 where A1, A 2 , Example: + An x - an (1)

DIFFERENTIATION
Definition;
Differentiation is an operation that allows us to find a function
that outputs the rate of change of one variable with respect to
another variable.
