Question

Multiply the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of a. (a - 6)(a 2 +6a + 36)

Answer 1

It's just a^3...
You can check to see if this's right

Answer 2

`a^(3)` -216

Explanation:

The given polynomial is :

`(a-6)(a^(2) +6a +36)`

Arranging in grid form:

`a^(2)` +6a +36

a
`a^(3)`
`+6a^(2)` +36a

-6
`-6a^(2)` -36 a -216

Adding the results:

`a^(3)` -216
