Question

(ii) – 3ab, –17ab, 8ab, – 4ab

hintHint:

The concept used in this question is the addition of polynomials.
○        Arrange the term in the decreasing order of their power.
○        To add polynomials simply add any like terms together.
○        Like terms are terms whose variables and exponents are the same

The correct answer is: - 16a2b


    Answer:
    • Step by step explanation:
    ○        Given:
    Expression:  – 3ab, –17a2b, 8ab, – 4ab
    ○        Step 1:
    ○        Simplify the expression.

                        ∴ (– 3ab) + ( –17ab) + ( 8ab ) + ( – 4ab )
    ○        Step 2:
    ○        Perform simple addition of like terms

                        rightwards double arrow– 3ab – 17ab + 8a2b  – 4ab

                        rightwards double arrow- 16a2b

    • Final Answer:

                          - 16a2b
