Question

What are the zeros of x^6-64 ?

Answer 1

The zeros are the x-interceps

Answer 2

intercepts

Answer 3

You can use the quadratic formula to find the zeros.

Answer 4

how do i do that?

Answer 5

OK, so the quadratic formula is -b+- sqrt(b^2-4ac) all over 2a

Answer 6

(8 + x3)(-8 + x3)

Answer 7

Simply using the formula for difference of squares would have been sufficient enough.
\(a^2 + b^2 = (a + b)(a - b)\)

\(x^6 - 64 = (x^3)^2 - 8^2 = (x^3 + 8)(x^3 - 8)\)
