Using the quadratic formula, the solutions are:
a) ![x = \frac{3 \pm \sqrt{41}}{4}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B3%20%5Cpm%20%5Csqrt%7B41%7D%7D%7B4%7D)
b) ![x = 1 \pm 2i](https://tex.z-dn.net/?f=x%20%3D%201%20%5Cpm%202i)
<h3>What is a quadratic function?</h3>
A quadratic function is given according to the following rule:
![y = ax^2 + bx + c](https://tex.z-dn.net/?f=y%20%3D%20ax%5E2%20%2B%20bx%20%2B%20c)
The solutions are:
![x_1 = \frac{-b + \sqrt{\Delta}}{2a}](https://tex.z-dn.net/?f=x_1%20%3D%20%5Cfrac%7B-b%20%2B%20%5Csqrt%7B%5CDelta%7D%7D%7B2a%7D)
![x_2 = \frac{-b - \sqrt{\Delta}}{2a}](https://tex.z-dn.net/?f=x_2%20%3D%20%5Cfrac%7B-b%20-%20%5Csqrt%7B%5CDelta%7D%7D%7B2a%7D)
In which:
![\Delta = b^2 - 4ac](https://tex.z-dn.net/?f=%5CDelta%20%3D%20b%5E2%20-%204ac)
Item a:
The coefficients are a = 2, b = -3, c = -4, hence:
Item b:
The coefficients are a = 1, b = 2, c = 2, hence:
