What is the quotient (3x2 + 8x − 3) ÷ (x + 3)?

3x-1

Step-by-step explanation:

We have the following expression:

Equating this equal to zero and completing the square then to get:

Arranging the terms which contain the same variable and moving the constant to the opposite side of the equation:

Factorize the leading coefficient:

Now complete the square and do not forget to balance the equation by adding the same constants to each side.

Re-writing it as perfect square:

Taking square root at both sides to get:

So,

Substiting it:

=
