This week I made a mistake with this question:

I remembered factoring 1-2-3, but when its three terms you cant always jump to product and sum, like I did. There needs to be a coefficient of 1 in front of  the x².

I thought we had to find two numbers that multiply to 3 and add to 11. Since I couldn’t find an answer, I asked classmates and found out you actually multiply the  6x² with the 3, to get 18. (This is one method, box method also works)

Find factors of 18 that add to 11, like 9 and 2.

Now we put this back, so we are able to factor.

Group and factor:

Important: Both brackets must look the same so we can take one out.

Final answer:
