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

Answer:

$a^{3}$ -216

Step-by-step 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
