Question

$$\frac{ 1 }{ x-2 } + \frac{ 3 }{ x } =2$$

Answer

x=3,1

Solution


Multiply both sides by the Least Common Denominator: \(x(x-2)\).
\[x+3(x-2)=2x(x-2)\]
Simplify.
\[4x-6=2{x}^{2}-4x\]
Move all terms to one side.
\[4x-6-2{x}^{2}+4x=0\]
Simplify  \(4x-6-2{x}^{2}+4x\)  to  \(8x-6-2{x}^{2}\).
\[8x-6-2{x}^{2}=0\]
Factor out the common term \(2\).
\[2(4x-3-{x}^{2})=0\]
Factor out the negative sign.
\[2\times -({x}^{2}-4x+3)=0\]
Divide both sides by \(2\).
\[-{x}^{2}+4x-3=0\]
Multiply both sides by \(-1\).
\[{x}^{2}-4x+3=0\]
Factor \({x}^{2}-4x+3\).
\[(x-3)(x-1)=0\]
Solve for \(x\).
\[x=3,1\]
