Question 83162: How do I solve using the quadratic equation this problem.
x + 1/x = 3/x + 3 Found 2 solutions by Mogana, Mona27:Answer by Mogana(4) (Show Source):
You can put this solution on YOUR website! x + 1/x = 3/x + 3
Multiply each individual term by x, we get
x * x + (1/x) *x = (3/x) *x + 3 *x
x^2+ 1 = 3 + 3x
Get all the terms to one side, we get
x^2 -3x-3 +1 =0
x^2 -3x -2 = 0
It is of the form ax^2+ bx +c =0
Where a =1, b =-3, c =-2
Now substitute in the equation to get roots.

You can make it into a quadratic equation by multiplying each term by x (to get rid of the x's in the denominators)
Now rearrange:
And use the quadratic formula to solve:
Which gives:
x=3.56 or x=-0.56
