Directions (11-15): In the following questions, two equations in x and y are given. Solve these equations and give answer

Q11. I. x² + 7x + 12 = 0
II. 4y ² = 36

if x>y
if x<y
if x≥y
if x≤y
x=y or relation cannot be established between x and y
Solution:

I. x² + 7x + 12 = 0
⇒ x = –3, –4
II. y² = 9
⇒ y = ± 3
y ≥ x

Q12. I. 2x ² +5x + 3 = 0
II. y ² + 3x + 2 = 0

if x>y
if x<y
if x≥y
if x≤y
x=y or relation cannot be established between x and y
Solution:

I. 2x² + 5x + 3= 0
⇒ 2x² + 2x + 3x + 3 = 0
⇒ (x + 1) (2x + 3) = 0
⇒ x = -1, -3/2
II. y² + 3y + 2 = 0
⇒ (y + 1) (y + 2) = 0
⇒ y = –1, –2
No relation

Q13. I. 2x + 3y = 5
II. 3x + 2y = 10

if x>y
if x<y
if x≥y
if x≤y
x=y or relation cannot be established between x and y

Q14. I. x² + 19x + 84 = 0
II. y² + 14y + 49 = 0

if x>y
if x<y
if x≥y
if x≤y
x=y or relation cannot be established between x and y
Solution:

I. x² +19x + 84 = 0
⇒ (x + 7) (x+ 12) = 0
⇒ x = -7, –12
II. y² + 14y + 49 = 0
⇒ (y + 7) ² = 0
⇒ y = –7
y ≥ x

Q15. I. 3x² + 4x + 1 = 0
II. 2y² + 3y + 1= 0

if x>y
if x<y
if x≥y
if x≤y
x=y or relation cannot be established between x and y
Solution:

I. 3x² + 4x + 1= 0
⇒ 3x² + 3x + x +1 = 0
⇒ (x + 1) (3x +1) = 0
⇒ x = -1, -1/3
II. 2y² + 3y + 1= 0
⇒ 2y² + 2y + y +1 = 0
⇒ (y + 1) (2y+ 1) = 0
⇒ y= -1,-1/2
No relation
