Question

Find the sum of the three expressions and choose the correct answer.

-8a 3 b + 3a2 b 2 - 5
2 + 5a 2 b 2
3a 3 b + 7 - 9a 2 b 2

Answer 1

`Only like terms can be added or subtracted`

Answer 2

Now like terms must have the same power of a and b

Answer 3

So one such like terms set would be = \(3a^2b^2, 5a^2b^2, -9a^2b^2\)

Answer 4

Can you tell the other such like terms ?

Answer 5

ok 3a^3b, -8a^3b?

Answer 6

Good
