2a + 2 (3a + 2)

I first multiplied the 2a by everything inside the bracket, giving:

6a squared + 4a

Then multiplied the 2 by everything inside the bracket, giving:

6a + 4

so in total I had:

6a squared + 4a + 6a + 4

which I simplified to:

6a squared + 10a + 4

The answer is actually:

8a + 4

Where did I go wrong?
