Question 1 • (OC27) MATH COLL ALGEBRA-1200710-S1-Degele-VOL7006P
The starting term is 3x²y. To get a monomial after addition, the added term must have the same variables raised to the same powers, so the terms combine into one term. Both −12x²y and 4x²y are like terms with 3x²y; the other choices have different exponents or variables.
