In order to simplify this, we can use polynomial long division.
So the quotient is
and the remainder is 0. This means that
or more simply
Note: consequently, this means that
(just multiply both sides by
)

it is like "long division" from grade school
x goes into x^3, x^2 times
x^2 times (x - 3) is (x^3 - 3x^2)
(x^3 + x^2) minus (x^3 -3x^2) is 4x^2 ___ bring down -10x
x goes into 4x^2, 4x times
4x times (x - 3) is (4x^2 - 12x)
(4x^2 - 10x) minus (4x^2 - 12x) is 2x ___ bring down -6
x goes into 2x, 2 times
2 times (x - 3) is (2x - 6)
(2x - 6) minus (2x - 6) is zero ___ no remainder
/x-3 = x^2 + 4x + 2
