Math Problem Statement

factor out 64-w3

Solution

To factor the expression 64w364 - w^3, we recognize it as a difference of cubes since 6464 is a perfect cube (64=4364 = 4^3) and w3w^3 is obviously a cube.

The difference of cubes formula is:

a3b3=(ab)(a2+ab+b2)a^3 - b^3 = (a - b)(a^2 + ab + b^2)

Here, a=4a = 4 and b=wb = w. So, applying the formula:

64w3=(4w)(16+4w+w2)64 - w^3 = (4 - w)(16 + 4w + w^2)

Thus, the factored form of 64w364 - w^3 is:

(4w)(16+4w+w2)(4 - w)(16 + 4w + w^2)
