Question

One of the factors of 8x^3 - 800x is
A. 8x
B. x + 10
C. x-10
D. All of the above

Answer 1

One of the factors would be D:all of the above

Answer 2

Answer:  D. All of the above

Step-by-step explanation:

The given expression :  $8x^3 - 800x$

We can see that the 8x is the greatest common factor of both the terns in the given polynomial.

Taking the GCF (8x) common as outside the expression , we get

$8x(x^2-100)\\\\=8x(x^2-(10)^2)$

Using the identity : $a^2-b^2=(a+b)(a-b)$

$8x(x+10)(x-10)$

Hence, the factors of the given expression are $8x,\ (x+10),\ (x-10)$
