Question

(ii) -12a2b2 and -6a2b2

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: -18a2b2


    Answer:


    • Step by step explanation:
    ○        Given:
    Expression: -12a2b2
    -6a2b2
    ○     Step 1:
    ○     Simplify the expression.
    ∴  (-12a2b2 ) + (  -6a2b2 )
    ○     Step 2:
    ○     Group the like terms.

                          rightwards double arrow-12a2b2 - 6a2b2
    ○     Step 3:
    ○     Perform simple addition of like terms

                         rightwards double arrow -12a2b2 - 6a2b2

                         rightwards double arrow -18a2b2

    • Final Answer:

                 -18a2b2
