Answer:
-35n+6
Explanation:
5n(-7n)+6
Okay so there is a term in front of another term in parentheses
This let's us know that we are going to distribute (multiply)
5n × -7n = -35n^2
The reason it's -35 it's because a positive times a negative is a negative
the reason it's n^2 it's because n × n = n^2
Now we can't forget the positive 6!
-35n + 6 is your answer
The reason we don't add the 6 to the -35n is because they are not like terms so therefore we cannot do anything further
The 6 does not have an n attached to it so we leave as it it
