Question

factor of polynomial x³- 8​

Answer 1

Answer:

x3 - 8 is an example of the difference of 2 cubes. The formula for the difference of 2 cubes is:

a3 - b3 = (a - b)(a2 + ab + b2)

So, let's say x = a, and 2 = b (Since 23 = 8)

Your answer should look like this:

(x - 2)(x2 + 8x + 4)

Answer 2

Answer:

(x-2) and (x² + 8x +4)is the factor of polynomial (x³- 8).

Step-by-step explanation:

x³- 8

=(x-2)(x² + 8x +4)

{because (a³ – b³) = (a-b)(a² + ab+b²)}
