How to factor 3x³+3x²-36

Step-by-step explanation:

Firstly, divide all parts of the equation by 3:

Now focus on the equation:

We know that the equation can be factored using x so we know that (x +- unknown) is the factor. We need to find the easiest way to factor this, lets find the factors of 12:

1 12

2 6

3 4

1 and 12 won't work so let's try 2 and 6, initially start as a negative 2:

=

We can confirm this is simplified by multiplying together:

=

Meaning it is simplified.

Now, put the equations together:
