1. The problem involves converting the roots $x_1$ and $x_2$ of a quadratic equation or any other context where these variables represent values that need conversion. 2. To convert $x_1$ and $x_2$, first identify the conversion rule or formula applicable (e.g., unit conversion, coordinate transformation). 3. Suppose the conversion is a linear transformation: $x' = a x + b$, where $a$ and $b$ are constants. 4. Apply this formula to each root: $$x_1' = a x_1 + b$$ $$x_2' = a x_2 + b$$ 5. This ensures both $x_1$ and $x_2$ are converted consistently. 6. If the conversion is different, please specify the exact rule or formula to apply. 7. Without a specific formula, the general approach is to substitute each $x_i$ into the conversion expression. Final converted values depend on the given conversion formula.
