Add: 7a²bc, -3abc², 3a²bc, 2abc²

Solution:

Given terms to add → 7a²bc, - 3abc², 3a²bc, 2abc²

⇒ 7a²bc + (- 3abc²) + 3a²bc + 2abc²

= (7a²bc + 3a²bc) + (-3abc² + 2abc²)

= 10 a²bc + (-1abc²)

= 10 a²bc - abc²

✦ Try This: Subtract, 25x²y³ from the sum of -17x²y³ and 43x²y³

Given, sum of -17x²y³ and 43x²y³ = -17x²y³ + 43x²y³ = 26x²y³
