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?

2x

-2x

1/2x

Morrison · Answer 1

X = - b/2a

Solving for a,

a = - b/2x

If b is the numerator, the denominator is - 2x

The second option is correct.
