Question

2x ² − 15 = 7x

17y = −7 − 6y ²

A) if x > y
B) if x < y
C) if x ≥ y
D) if x ≤ y
E) x = y or no realtion can be established

Solution

(e); 2x² - 10x + 3x - 15 = 0

2x(x - 5) + 3(x - 5) = 0

x = -3/5, 5

6y² + 14y + 3y + 7 = 0

2y(3y + 7) + 1(3y + 7)= 0

y = -1/2, -7/3, no realtion can be established


						(e); 2x² - 10x + 3x - 15 = 0
       2x(x - 5) + 3(x - 5) = 0
       x = -3/5, 5
       6y² + 14y + 3y + 7 = 0
       2y(3y + 7) + 1(3y + 7)= 0
       y = -1/2, -7/3, no realtion can be established

Solution
