Factor completely x3 − 2x2 − 8x 16. (x 2)(x2 8) (x − 2)(x2 8) (x 2)(x2 − 8) (x − 2)(x2 − 8).
dybincka [34]

Answer:

D) (x - 2)(x² - 8)

Step-by-step explanation:

Separate the polynomial into two groups of two terms and factor out the common value from each group.  If the values factored out from each group are the same, then you can use the grouping method.  The factors will be the outside terms and the common factor.

   x³ - 2x²     +     -8x + 16

=  x²(x - 2)      +     -8(x - 2)

= (x² - 8)(x - 2)

Hi, Which of these percentages is closest in value to 7/9
Gnoma [55]
To find a percentage, you need to divide 7 by 9 to find out what 7/9 is.
It turns out to be 0.777 repeating. 
To find a percentage, you need to move the decimal place over by two to the right, so 7/9 is equals to 77.77%.
If you round that, then 77.77% is closest to 78%.


Hope this helps!
