I had to expand and simplify this formula and I got it wrong.
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?
