Answer:
Hey, you spelled this equation wrong and that is why you can't get a correct answer, doofus
Step-by-step explanation:
(x - 1)
Given
f(x) = x³ - 2x² - 19x + 20
The sum of the coefficients is 1 - 2 - 19 + 20 = 0
This means that x = 1 is a root and (x - 1) is a factor of f(x)

I found the ansewr by dividing both of the numbers to equal tthat
I got 7.1 x 10^(-11) but it's been a few years so I could've done it wrong
The answer is .64
