Question

# (ii) -12a^{2}b^{2} and -6a^{2}b^{2}

Hint:

### 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: -12a^{2}b^{2}

-6a^{2}b^{2}

○ Step 1:

○ Simplify the expression.

∴ (-12a^{2}b^{2} ) + ( -6a^{2}b^{2} )

○ Step 2:

○ Group the like terms.

-12a^{2}b^{2} - 6a^{2}b^{2}

○ Step 3:

○ Perform simple addition of like terms

-12a^{2}b^{2} - 6a^{2}b^{2}

-18a^{2}b^{2}

- Final Answer:

-18a^{2}b^{2}

^{2}b

^{2}- 6a

^{2}b

^{2}

○ Step 3:

○ Perform simple addition of like terms

^{2}b

^{2}- 6a

^{2}b

^{2}

^{2}b

^{2}

^{2}b
