Give answer If
a. x ˃ y
b. x ≥ y
c. x ˂ y
d. x ≤ y
e. x = y or the relationship cannot be established
I. $${x^2}$$ - 7x + 10 = 0
II. $${y^2}$$ + 11y + 10 = 0
I. $${x^2}$$ + 28x + 192 = 0
II. $${y^2}$$ + 16y + 48 = 0
I. $${x^2}$$ + 8x + 15 = 0
II. $${y^2}$$ + 11y + 30 = 0
I. x = $$\sqrt {3136} $$
II.$$ {y^2}$$ = 3136
