Remark
You'll see it a whole lot easier if you make a substitution so that it looks like something you have already seen
Solution
let y = x^2
x^4 = x^2 * x^2
x^4 = y * y
x^4 = y^2
Now the expression becomes
y^2 + 8 y - 9 = z
(y + 9)(y - 1) = z
Now put the x^2 back in.
(x^2 + 9) ( x^2 - 1) = z
x^2 - 1 becomes x + 1 and x - 1. At this level x^2 + 9 can't be factored.
Answer
(x^2 + 9) (x + 1)(x - 1)
What grade is that is that 4th or 5th grade
Answer:
The dilation scale factor is .
Step-by-step explanation:
The image is the dilated form of its preimage if and only if the following conditions are observed:
1)
2)
3)
4)
5)
If we know that , , , , , , and , then the coefficients are, respectively:
, , ,
As , we conclude that the dilation scale factor applied in the preimage is equal to .
