(i). a2 – 9a + 20 = 0, (ii). 2b2 – 5b – 12 = 0 to solve both the equations to find the values of a and b ?

– by 0

A. If a ≥ b
B. If the relationship between a and b cannot be established
C.  If a < b
D. If a ≤ b

Explanation:

I. (a – 5)(a – 4) = 0
=> a = 5, 4
II. (2b + 3)(b – 4) = 0
=> b = 4, -3/2 => a ≥ b
