How do you do this question?
I am not sure if this right.
1. solve rational equation
A) (x+3)/(x1)=2x+1
x+3=(2x+1)(x1)
x+3=2x^2  2x + x  1
??

collect all like terms to get a quadratic equation
2x^2  3x  4 = 0
use the formula to solve for x

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

correction  Math  Reiny, Tuesday, January 10, 2012 at 1:22am
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
