    Simplify the rational expressions. State any excluded values. Show your work.

    that's a polynomial expression. A rational expression is a fraction

    is that the exact way it's written? there's no numerator/denominator?

    2x/x^2+3x-10 sorry didn't include the division.

    like this? \[\frac{ 2x }{ x^2+3x-10 }\]

    Usually you'd factor like this and something will cancel from the numerator and denominator. \[\frac{ 2x }{ (x+5)(x-2) }\] Since nothing canceled, the original is already simplified. For excluded values set the denominator equal to 0. \[(x + 5)(x - 2) = 0\] So you need to solve \(x+5=0\) and \(x-2=0\)

    Alright. x+5-5=0-5 x= -5 X-2+2=0+2 = 2

    yes, so -5 and 2 are the excluded values
