Factor the following polynomial completely,

OPTION C

Step-by-step explanation:

The given polynomial is: 1280 x¹¹ - 405 x⁷.

The least power of the variable is taken common outside. So we get:

x⁷{1280 x⁴ - 405}

Now, 5 is a factor of both 1280 and 405.

So, it can be written as:

5x⁷{256x⁴ - 81}

We know that

Also, 256 = 16² and 81 = 9².

Therefore, this can be rewritten as:

Using the above formula, a = 16x² and b = 9.

Therefore, this becomes:

can again be factorized with a = 16x and b = 3.

Therefore, it would be:

Hence, OPTION C is the answer.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
