Step-by-step explanation:B
The factors of the quadratic equation are (x+3) and (x-15).
<h2 /><h2>Given to us</h2>
<h3>To find</h3>
The factors of
.
<h3 /><h3>Solution</h3>

As we can see in the quadratic equation the value of ac is -45x². therefore, we need to divide -12x into two parts such that their sum must give -12x and their product gives us -45x².
therefore, dividing -12x into -15x and 3x,

Taking common out,

Hence, the factors of the quadratic equation are (x+3) and (x-15).

Answer:
f(4) = 1
Step-by-step explanation:
f(4) = what?
So if we know that x, aka 4, is technicially f is greater then 2, so you can plug in x as 4. So that means 5(4) - 19 = 20 - 19 = 1, so f(4) = 1
