Using the Quadratic Equation, solve the following for X: 4X{eq}^2 {/eq} + 5X + 6 = 0

## Question:

Using the Quadratic Equation, solve the following for X: 4X{eq}^2 {/eq} + 5X + 6 = 0

## Quadratic Equation:

The quadratic equation has three options for its solution:

- Two different real roots
- Two equal real roots
- Two conjugate complex roots

This equation has a quadratic formula that defines the solutions using the coefficients of the equation:

$$\begin{align}
x_{1,2} &= \frac { -b \pm \sqrt{b^2-4ac}}{2a} && \left[ \textrm {Second grade solutions formula} \quad ax^2+bx+c=0 \right] \\[0.3cm]
\end{align}
$$
