In physics and engineering the quality factor or Q factor is a dimensionless parameter that describes how under-damped an oscillator or resonator is, and characterizes a resonator's bandwidth relative to its center frequency.
The Q factor, or quality factor, of a coil can be measured by determining the ratio of its inductive reactance to its resistance at a specific frequency. This is typically done by applying an AC signal to the coil and measuring the voltage across it and the current flowing through it. The Q factor is calculated using the formula ( Q = \frac{X_L}{R} ), where ( X_L ) is the inductive reactance and ( R ) is the resistance. Alternatively, it can be measured using the bandwidth method, where the Q factor is derived from the resonant frequency and the bandwidth of the coil's response curve.

2(q^2 - 5) or 2(q - the square root of 5)(q + the square root of 5)
Consider a number k. Let m be the square root of k : since k is not a square number, m is not an integer and so m cannot be a factor of k.Suppose p is a factor of k and suppose p< m.Then k has another factor q such that k = p*q and since p < m, then q> m.Thus, for every factor smaller than the square root, there is another factor that is larger than the square root. That is, the factors come is distinct pairs and so there is an even number of factors.
impedance/resistance
The Q factor of a coil, sometimes called the unloaded Q factor, is the ratio of the energy stored in the coil to the energy dissipated in the resistance of the wire.
In a RLC series circuit the Q factor magnify the voltage to the circuit.
The Q factor is describing how sharp the dropoff of the filter is relative to the pass band. Wikipedia has a decent writeup on Q factor. The more components you use to make the filter, and the lower the cutoff frequency, the higher the Q will be.
yes ,Q factor is ratio of energy stored to energy dissipated

Q is the general idea of component quality, mainly in AC circuits. It is equal to reactance divided by resistance. The Q factor of an entire circuit can also be computed the same way. In general, adding resistance decreases the circuit or component Q. The "Q" factor is a empirical number to imply the acuteness of a circuit to discriminate surrounding influences and act on the Q of the circuit. The higher the Q THE SHARPER THE RESPONSE.
The quality factor q affects the overall performance of the system by determining how efficiently energy is transferred and stored within the system. A higher quality factor q indicates better performance with less energy loss, while a lower quality factor q indicates poorer performance with more energy loss.

Minimize circuit resistance.
Q is often used to connote "electric charge".The Q factor of tuned circuits is a measure of "quality factor". It is a measure of how well the tuned circuit selects wanted frequencies and rejects the unwanted.
