Answer:
3
Step-by-step explanation:
because you would divide 9 by 3 because 9 cakes and then 3 bags of flower 1 bag of flower to 3 cakes
(-2 x -3) - (3x^2 - 8x + 9)
-6 - 9x - 17x
-6 - -8x
-14x

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)
I thing c is the right answer
