Question بين ضرايب معادله برقرار باشد، كدام گَينه، يكى از ريشههاى معادله |است؟ $$\begin{array}{rr} \frac{c}{a} & 1 \\ \frac{c}{\mu a} & \mu \\ -\frac{c}{\mu a} & \mu \\ -\frac{c}{a} & \kappa \end{array}$$

Studdy Solution
Observe the roots obtained from the quadratic formula and compare with the options provided. The correct root should match one of these options directly or by simplified form.
Given:
$$x = \frac{-9a - c \pm \sqrt{81a^2 - 18ac + c^2}}{6a}$$
The correct option appears to be:
$$x = -\frac{c}{a}$$
This matches the form of Option 4:
$$-\frac{c}{a}$$
Solution: The root of the equation that matches one of the given options is $-\frac{c}{a}$.
