Which equation represents the average of the x-intercepts for 4x^2-24x+20

Number of x intercepts in this equation is 2 because max power in the function is 2. number of x intercepts is determined by "highest power".

let x1 represent first x intercept and
let x2 represent second x intercept

Formula for finding average of x intercepts is logicaly:
Avg = (x1 + x2)/2

we want to find x1 and x2
4x^2 - 24x + 20 = 0
x^2 - 6x + 5 = 0

x1 = 5
x2 = 1

Avg = 3

Hold on lemme do the work
