There are two equations (1) and (II) are given. You have to solve both the equations and answer the following questions.
I. x2 - 2 (b - a) x = (102 - x)
Il. y2 + (a + b) y + 84 = 0
III. z2 + (a + b)z + (PQ) = 0
Note:
i) 24a + 12b = 324
ii) 18a - 6b = 48
iii) smaller root in equation I is P and Higher root in equation II is Q
