Answer:
Factoring is taking the greatest factor of an equation/expression and putting it behind parenthesis.
For example:
2+4: Factor it
2 is the greatest factor of the two
SO
2(1+2)
Ill give you a try it and you can factor it. I might check it later on.
42+ 36
If you are looking for something harder:
4x^4+ 6x^6
