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)
The milligrams of sodium in a 20 ounce sports drink is 275 milligrams.
Work:
I divided 110 by 8 which gave me 13.75
13.75 is the milligrams of sodium in each ounce.
I then divided it by 20 and got 275 the number of milligrams in a 20 ounce drink.
