- I. x^2 – 14x + 48 = 0 II. y^2 – 9y + 20 = 0
Question 1:
I. x^2 – 14x + 48 = 0 II. y^2 – 9y + 20 = 0
A. if x > y
Feedback According to the given equations:
I. x^2 – 14x + 48 = 0
x^2 – 8x – 6x + 48 = 0
x (x – 8) – 6 (x – 8) = 0
(x – 8)(x – 6) = 0
x = 8, 6
II. y^2 – 9y + 20 = 0
y^2 – 5y – 4y + 20 = 0
y (y – 5) – 4 (y – 5) = 0
(y – 4)(y – 5) = 0
y = 4, 5
After comparison of both equations, the conclusion is x > y
Hence, option A is correct.

x (x – 8) – 6 (x – 8) = 0
(x – 8)(x – 6) = 0
x = 8, 6
II. y^2 – 9y + 20 = 0
y^2 – 5y – 4y + 20 = 0
y (y – 5) – 4 (y – 5) = 0
(y – 4)(y – 5) = 0
y = 4, 5
After comparison of both equations, the conclusion is x > y
Hence, option A is correct.
B. if x ≥ y
C. if x ≤ y
D. if x < y
