Factor completely 5ax2 - 20x3 + 2a - 8x.

(a-4x) (5x^2+2)

Step-by-step explanation:

5ax^2 - 20x^3 + 2a - 8x.

We will factor by grouping.

Take 5x^2 out of the first 2 terms and 2 out of the last 2 terms

5x^2 (a-4x) + 2 (a - 4x)

Now we can factor a (a-4x) out

(a-4x) (5x^2+2)

(5x^2 + 2) (a - 4x).

Step-by-step explanation:

5ax2 - 20x3 + 2a - 8x

Factor by grouping:

5x^2 (a - 4x) + 2 (a - 4x)

= (5x^2 + 2) (a - 4x).
