Question
solve: \\(\frac{x}{3} = \frac{1}{x - 2}\\)\
\\(\bigcirc\\) x=3, x=-1\
\\(\bigcirc\\) x=2\
\\(\bigcirc\\) x=-3, x=1\
\\(\bigcirc\\) x=0
Step1: Cross - multiply the equation
Given the equation \(\frac{x}{3}=\frac{1}{x - 2}\), cross - multiplying (which is valid when \(x
eq2\) to avoid division by zero) gives us \(x(x - 2)=3\times1\).
Step2: Expand and simplify the equation
Expanding the left - hand side, we get \(x^{2}-2x = 3\). Rearranging this equation to the standard quadratic form \(ax^{2}+bx + c = 0\), we have \(x^{2}-2x-3 = 0\).
Step3: Factor the quadratic equation
We need to find two numbers that multiply to \(- 3\) and add up to \(-2\). The numbers are \(-3\) and \(1\). So, the quadratic equation \(x^{2}-2x - 3=0\) can be factored as \((x - 3)(x+1)=0\).
Step4: Solve for x
Using the zero - product property, if \((x - 3)(x + 1)=0\), then either \(x-3 = 0\) (which gives \(x = 3\)) or \(x + 1=0\) (which gives \(x=-1\)). We also need to check that these values do not make the original denominator zero. For \(x = 3\), the denominator \(x - 2=3 - 2 = 1
eq0\). For \(x=-1\), the denominator \(x - 2=-1 - 2=-3
eq0\).
