Answer:

The denominator of the fraction is 2x and the answer is a= -[tex]\frac{b}{2x}[/tex]

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:

[tex]x= \frac{-b}{2a}[/tex]

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:

[tex]a= \frac{-b}{2x}[/tex]

Answer:

B.

a= -b/2x
