Step-by-step explanation:
x³ - 4x = 0
x (x² - 4) = 0
x (x + 2) (x - 2) = 0
Thus the answer is (b) (-2 , 0) , (0 , 0) , (2 , 0)
Answer:
$7 total
Step-by-step explanation:
$5 + $2 = $7
12% would be bigger because it is a whole number other then the fraction.
Looking at <span>4x3 + x2 – 8x – 2, I see immediately that x^2 can be factored out of the first 2 terms => 4x^2(x+1)
and -2 out of the last 2 terms => -2(4x+1).
Notice how the factor (4x+1) shows up twice.
We can factor this (4x+1) out, obtaining (x^2 - 2) (4x+1). These are the desired factors, found "by grouping."

The coordinates are (6,-9) (-12,-3) (0,-7)
you put 6 in the place of x to get 6+3y=-21 then you must take 6 away from each side to get 3y= -27 then divide each side by 3 so -27 divided by 3 is -9. do this for all of them! hope it helped!
