    Find inflection points of polynomials.

    i am quite aware that the (x^2-x) comes out. I have been for the last 12 hours. I am having trouble with what comes after it. But I'll go review my algebra. Thank you both for nothing.

    I am having trouble finding the something. Is that clear?

    Find inflection points of polynomials.

    Should the parenthesis come off the second factor ? So the values are included with the rest ?

    Can you help me see where it's wrong ?

    Find inflection points of polynomials.

    (x^2+x)(x^2+x) +(2x-1)(4x)(2x-1)(-2) = (x^2+x)(x^2+x)+ -8x(4x^2-4x+1) =(x^2+x)(x^2+x)+ -32x^3-32x^2-8x

    Are you saying get rid of the -2

    Find inflection points of polynomials.

    Ok first step in factoring out (x^2-x) I get -2(x^2-x)(x^2-x)+(2x-1)(4x)(2x-1) Should I have canceled the second (x^2-x) because of the denominator ?

    Find inflection points of polynomials.

    I get left with -2(x^2-x)(x^2-x)+2x-1(4x+1)

    also that -2, can that move in front of the derivative?

    Find maxima/minima of polynomials

    It was multiple choice on khan academy. for which values of x is the function a local minimum or maximum. i can't remember which. But -1/3 was the correct answer per the software (s-word again)
