This equation resembles a polynomial in terms of \( x = \frac{(a - \varepsilon)}{b} \). When you rewrite it, it becomes \( x^4 - 3x^2 + 1 = 0 \), which is a quadratic equation in terms of \( x^2 \). You can set \( y = x^2 \) to get the factorable form as \( y^2 - 3y + 1 = 0 \). Using the quadratic formula gives you solutions for \( y \), and from there, you can find the corresponding \( x \) values, which in turn leads you to the values of \( a \) and \( \varepsilon \). Once you have obtained the roots, don’t forget to verify whether they fit the original equation and check if there are any restrictions on \( a \) or \( \varepsilon \) that might affect the solutions. Common mistakes include overlooking these conditions or forgetting to check for extraneous solutions that arise from squaring both sides or simplifying.
