![## Solving Quadratic Equations
### Problem Statement
**Solve the following quadratic equation however you choose to do so: SHOW WORK**
\[ 5x^2 + 8x - 4 = 0 \]
### Instructions
1. Choose a method to solve the quadratic equation. You can use factoring, completing the square, or the quadratic formula.
2. Show all steps and calculations that lead to your solution.
### Examples of Solution Methods
#### Method 1: Quadratic Formula
The quadratic formula is given by:
\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]
For the given equation \( 5x^2 + 8x - 4 = 0 \), identify the coefficients \( a = 5 \), \( b = 8 \), and \( c = -4 \).
Substitute these values into the quadratic formula and solve for \( x \).
#### Method 2: Factoring
If the quadratic equation can be factored into a product of binomials, set each factor equal to zero and solve for \( x \).
#### Method 3: Completing the Square
Rearrange the equation and complete the square to solve for \( x \).
### Note:
Include detailed steps for your chosen method to ensure clarity and accuracy.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fba45ef30-7373-40a6-93b1-6069d924f96b%2Fe46eb7ef-1f7a-4c52-aa74-7f37b44bb706%2F7vis3q_processed.jpeg&w=3840&q=75)
