The factors of the given quadratic expression, 2x² - 4x - 16, are 2, (x +2), and (x -4)
<h3>Factoring a Quadratic expression </h3>
From the question, we are to determine the each of the factors of the given quadratic expression
The given quadratic expression is
2x² - 4x - 16
Factoring
2x² - 4x - 16
First, factor out 2
That is,
2(x² - 2x - 8)
Now, we will factor x² - 2x - 8
x² - 2x - 8
x² - 4x + 2x - 8
x(x - 4) +2(x -4)
(x +2)(x -4)
Thus,
2x² - 4x - 16 = 2(x +2)(x -4)
Hence, the factors of the given quadratic expression, 2x² - 4x - 16, are 2, (x +2), and (x -4)

•Slope is defined as "rise over run."
•Make sure that the line is straight. You can't find the slope of a line that isn't straight.
•Coordinates are the xand y points written as (x, y). It doesn't matter which points you pick, as long as they're different points on the same line.
•It doesn't matter which one you pick, as long as it stays the same throughout the calculation. The dominant coordinates will be x1 and y1. The other coordinates will be x2 and y2.
•Set up the equation using the y-coordinates on top and the x-coordinates on bottom.
•Subtract the two y-coordinates from one another.
•Divide the y-coordinate's result with the x-coordinate's result. Reduce the number if at all possible.
In finding the sum of 2+5 you would go right on the number line, while in finding the sum of -2+(-5) you would go left on the number line
