Answer:
The denominator of the fraction is 2x and the answer is a= -![\frac{b}{2x}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7B2x%7D)
Step-by-step explanation:
Suppose we have a quadratic equation of the form:
ax²+bx+c
The axis of symmetry of the parabola is given by:
![x= \frac{-b}{2a}](https://tex.z-dn.net/?f=x%3D%20%5Cfrac%7B-b%7D%7B2a%7D)
From here, we must clear the value of a.
For this, we follow the following steps:
1) Pass 2a multiplying to the other side of the equation:
2ax=-b
2) Clear the value of a by passing 2x to divide:
![a= \frac{-b}{2x}](https://tex.z-dn.net/?f=a%3D%20%5Cfrac%7B-b%7D%7B2x%7D)
