# Thread: Find all real or imaginary solutions.

1. ## Find all real or imaginary solutions.

1/x +1/x minus 1 =3/2 I try LCD and got 1 answer right out of 2.

Minus= subtract. My subract button dont work.

X cannot =0
X cannot =1
I plugin 2 into x and

2. ## Re: Find all real or imaginary solutions.

learn latex for an easier time for people to answer you.

If the question is
$\displaystyle \frac{1}{x} + \frac{1}{x} - 1 = \frac{3}{2}$, then

$\displaystyle \frac{2}{x} = \frac{5}{2}$. x=2 is not a solution, but the equation is easily solved through basic algebra.

3. ## Re: Find all real or imaginary solutions.

If the problem is $\displaystyle \frac{1}{x}+ \frac{1}{x- 1}= \frac{3}{2}$, then multiplying both sides by 2x(x- 1) reduces this to a quadratic equation.

Do you normally solve math problems by "plugging in" numbers at random?
