Answer:

x = 3 is the line of symmetry.

Step-by-step explanation:

In this question we have to find the equation of line of symmetry which is the average of x-intercepts.

Given quadratic function is f(x) = 4x² - 24x + 20

Now we know line of symmetry is denoted by x = -\frac{b}{2a}

From the quadratic function

a = 4

and b = -24

therefore, equation of symmetry will be x = -[\frac{-24}{(2)(4)}]

x = 3

Therefore, x = 3 is the line of symmetry for the given function.

Which binomials below is a factor of this trinomial 5x^2-5x-100
34kurt
We are asked to determine the correct factorization of the given trinomial which is 5x² - 5x -100. The solution to this problem is shown below:
5x² - 5x - 100 let the problem equal to zero such as:
5x² - 5x - 100 = 0 , factor out 5 from the given trinomial
5(x²-x-20) = 0
5 (x-5)(x+4) = 0

The correct factor is 5(x-5)(x+4).
