1/4 = 3/12
3/12 < 5/12
Therefore, 5/12 is greater than 1/4
Answer:
P(x) = x + 2
Piden: A = P(P(P(P(3))))
P(3); x = 3
P(3) = 3 + 2 = 5
A = P(P(P(P(3))))
A = P(P(P(5)))
P(5); x = 5
P(5) = 5 + 2 = 7
A = P(P(P(5)))
A = P(P(7))
P(7); x = 7
P(7) = 7 + 2 = 9
A = P(P(7))
A = P(9)
P(9); x = 9
P(9) = 9 + 2 = 11
→ A = P(P(P(P(3)))) = 11

So focusing on x^4 + 5x^2 - 36, we will be completing the square. Firstly, what two terms have a product of -36x^4 and a sum of 5x^2? That would be 9x^2 and -4x^2. Replace 5x^2 with 9x^2 - 4x^2: 
Next, factor x^4 + 9x^2 and -4x^2 - 36 separately. Make sure that they have the same quantity inside of the parentheses: 
Now you can rewrite this as
, however this is not completely factored. With (x^2 - 4), we are using the difference of squares, which is
. Applying that here, we have
. x^4 + 5x^2 - 36 is completely factored.
Next, focusing now on 2x^2 + 9x - 5, we will also be completing the square. What two terms have a product of -10x^2 and a sum of 9x? That would be 10x and -x. Replace 9x with 10x - x: 
Next, factor 2x^2 + 10x and -x - 5 separately. Make sure that they have the same quantity on the inside: 
Now you can rewrite the equation as
. 2x^2 + 9x - 5 is completely factored.

Answer:
0.7x/0.8y = x/y * 0.7/0.8 = x/y * 0.875
So the fraction is reduced by 12.5%
