Question

The axis of symmetry for a quadratic equation can be found using the formula x =-b/2a , where a and b are coefficients in the quadratic equation and x represents the values along a vertical line on the coordinate plane. When the equation is solved for a, such that b is the numerator of the resulting fraction, what is the denominator of the fraction?

Answer 1

Answer:

B

Step-by-step explanation:

a = -b/2x

Answer 2

Answer:

2x

Step-by-step explanation:

Solve the equation for a as follows:

First multiply both sides by 2a:

$(2a)x=-b$ and then divide both sides by 2x:

$a=-\frac{b}{2x}$
