I don’t understand is there more to the question?
Now, to find 'x' you will apply the Null Factor Law. This means you will now let 'x' = 0, and simply move the -2 over to the other side to find your answer. Note: since we are using a perfect square, x will only have one value since there is only one answer (x-2) in the brackets, meaning in this case we can ignore the exponent (as the answers will be the same). If there was more than one answer in the bracket (e.g. (x-4) and (x-6)), then we would apply Null Factor Law to both brackets and solve for x.
(x−2)=5
x=5+2
x=7
We can check each of these using the Pythagorean Theorem,
Option A:
.25 + 1.44 = 1.691.69 = 1.69
This option works
Option B
1 + 4 = 9
5 ≠ 9
This option does not work, but let's check the others to make sure
Option C:
36 + 64 = 100
100 = 100
This option works
Option D:
9 + 16 = 25
25 = 25
This option works
So, after doing the calculations, we see that option B does not work
Answer:
(x + 2) + (–5x + 4) / (x² – 2x + 1)
Step-by-step explanation:
(x³ – 8 x + 6) ÷ (x² – 2x + 1)
The operation can be carried out as follow:
Please see attached photo for details.
(x³ – 8 x + 6) ÷ (x² – 2x + 1) =
(x + 2) + (–5x + 4) / (x² – 2x + 1)
2.25x15= blah blah blah, and boom there is your answer
