How do you do this question?
I am not sure if this right.


1. solve rational equation
A) (x+3)/(x-1)=2x+1

x+3=(2x+1)(x-1)
x+3=2x^2 - 2x + x - 1

??

  • Math -

    collect all like terms to get a quadratic equation

    2x^2 - 3x - 4 = 0
    use the formula to solve for x

  • Math -

    So I have to use quadratic formula right? If so, no wonder I don't get the answer

  • correction - Math -

    I think I added the x terms up incorrectly

    should have been

    2x^2 - 2x -4 = 0
    divide by 2
    x^2 - x - 2 = 0
    now it factors
    x(-2)(x+1) = 0
    x = 2 or x = -1
