How do you factor 1/2x^3-x so that the zeroes can be found? Thank you-Adriana

  • Algebra -

    I think you mean

    1/(2x^3-x)

    factoring the denominator
    x(2x^2-1)= x(xsqrt2-1)(xsqrt2+1)

  • Algebra -

    (1/2)x(x^2 - 2) = 0
    x = 0 or x = ± √2

    See how the same question can be interpreted in more than one way if you don't use brackets?

    I read it as (1/2)x^3-x
    bobpursley read it as 1/(2x^3-x)
    or why not 1/(2x^3) - x ?
