II. 20y^2 + y - 12 = 0

a)
b)
c)
d)
e)
I. 20 x^2 – 31 x + 12 = 0
(4 x - 3) (5x – 4) = 0
x = (3/4), (4/5)
II. 20y^2 + y – 12 = 0
or, (4y – 3) (5y + 4) = 0
y = (3/4), (-4/5)
Hence x ≥ y

27. I. 2x^2 - 27x + 91 = 0
II. 2y^2 + y - 136 = 0

a)
b)
c)
d)
e)
I. 2x^2 –27x + 91 = 0
or, (x– 7) (2x – 13) = 0
x = 7, (13/2)
II. 2y^2 + y –136 = 0
or, (y – 8) (2y + 17)= 0
y = 8, (-17/2)

28. I. 2x -13 √x + 21 = 0
II. 2y -15 √y + 28 = 0

a)
b)
c)
d)
e)
I. 2x – 13√x + 21 =0
(√x – 3) ( 2√x –7) = 0
√x = 3, 7/2
x = 9, 49/4
II. 2y – 15√y + 28 =0
or, (2 √y –7) ( √y – 4) = 0
√y = 4, 7/2
y = 49/4, 16, Hence, x ≤ y

29. I. x^2 = 3136
II. y^2 = 1764

a)
b)
c)
d)
e)
I. x^2 = 3136
x = ±56
II. y^2 = 1764
y = ±42

30.I. x^2 - 20x + 91 = 0
II. y^2 - 6y - 91 = 0

a)
b)
c)
d)
e)
I. x^2 – 20 x + 91 = 0
(x –7) (x – 13)= 0
x = 7, 13
II. y^2 – 6 y – 91 = 0
(y –13) (y + 7) = 0
y = 13, –7
