Question

find the sum 9y^2+7y^2

Answer 1

Since the both numbers have the same base, they can be added together just like normal numbers. Does that make sense?

Answer 2

So it will be like 16^2?

Answer 3

16y^2 ** (Don't forget the y)

Answer 4

\[9y^2+7y^2 = 16y^2\]

The base gets carried over since it's the same. :)

Answer 5

They are like terms so you could just add them together but the y^2 stays the same so it becomes 16y^2

Answer 6

Thanks.(:
