Find roots of polynomial $$ p(x) = x^2-\frac{4}{3}x+\frac{1}{3} $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 1\\[1 em]x_2 &= \frac{ 1 }{ 3 } \end{aligned} $$Explanation
Step 1:
Get rid of fractions by multipling equation by $ \color{blue}{ 3 } $.
$$ \begin{aligned} x^2-\frac{4}{3}x+\frac{1}{3} & = 0 ~~~ / \cdot \color{blue}{ 3 } \\[1 em] 3x^2-4x+1 & = 0 \end{aligned} $$Step 2:
The solutions of $ 3x^2-4x+1 = 0 $ are: $ x = \dfrac{ 1 }{ 3 } ~ \text{and} ~ x = 1$.
