Answers :
11) Answer: B
3x2 – 5x – 42 = 0
3x2 + 9x – 14x – 42 = 0
3x (x + 3) – 14 (x + 3) = 0
(3x – 14) (x + 3) = 0
x = 14/3, -3 = 4.667, -3
4y2 + 9y – 55 = 0
4y2 + 20y – 11y – 55 = 0
4y (y + 5) – 11 (y + 5) = 0
(4y – 11) (y + 5) = 0
y = 11/4, -5 = 2.75, -5
Hence, the relationship between x and y cannot be determined
12) Answer: A
4x2 – 25x + 36 = 0
4x2 – 16x – 9x + 36 = 0
4x (x – 4) – 9 (x – 4) = 0
(4x – 9) (x – 4) = 0
x = 2.25, 4
2y2 – 25y + 72 = 0
2y2 – 16y – 9y + 72 = 0
2y (y – 8) – 9 (y – 8) = 0
(2y – 9) (y – 8) = 0
y = 4.5, 8
Hence, x < y
13) Answer: A
6x² + 77x + 121 = 0
=> 6x2 + 66x + 11x + 121 = 0
=> 6x(x + 11) + 11(x + 11) = 0
=> (6x + 11)(x + 11) = 0
=> x = -11/6, -11
y² + 30y + 225 = 0
=> y2 + 15x + 15x + 225 = 0
=>y(y + 15) + 15(y + 15) = 0
=> (y + 15)(y + 15) = 0
=> y = -15, -15
Hence, x > y
14) Answer: E
4x² – 13x + 9 = 0
=> 4x2 – 4x – 9x + 9 = 0
=> 4x(x – 1) – 9(x – 1) = 0
=> (4x – 9)(x – 1) = 0
=> x = 9/4, 1
4y2 + 13y + 3 = 0
=> 4y2 + 12y + y + 3 = 0
=> 4y(y + 3) + 1(y + 3) = 0
=> (4y + 1)(y + 3) = 0
=> y = -1/4, -3
Hence, x > y
15) Answer: E
3x2 + 8x – 35 = 0
=>3x2 + 15x – 7x – 35 = 0
=> 3x(x + 5) – 7(x + 5) = 0
=> (3x – 7)(x + 5) = 0
=> x = 7/3, -5
y2 + 2y – 195 = 0
=> y2 + 15y – 13y – 195 = 0
=>y(y + 15) – 13(y + 15) = 0
=> (y + 15)(y – 13) = 0
=> y = -15, 13
Hence, the relationship between x and y cannot be determined.
16) Answer: C
2x² + 13x + 21 = 0
=> 2x2 + 6x + 7x + 21 = 0
=> 2x(x + 3) + 7(x + 3) = 0
=> (2x + 7)(x + 3) = 0
=> x = -7/2, -3
5y² + 11y – 36 = 0
=>5y2 + 20y – 9y – 36 = 0
=> 5y(y + 4) – 9(y + 4) = 0
=> (5y – 9)(y + 4) = 0
=> y = 9/5, -4
Hence, the relationship between x and y cannot be determined.
17) Answer: A
x2 – 20x + 75 = 0
x2 – 15x -5x + 75 = 0
(x – 15) (x – 5) = 0
x = 15, 5
2y2 – 14y + 24 = 0
2y2 – 8y – 6y + 24 = 0
2y (y – 4) – 6 (y – 4) = 0
(2y – 6) (y – 4) = 0
y = 3, 4
Hence, x > y
18) Answer: E
2x – 3y = -1 –> (1)
3x – 5y = 0 —> (2)
(1) * 3 = > 6x – 9y – 3 –> (3)
(2) * 2 = > 6x – 10y = 0 –> (4)
Subtract the equations (3) and (4), we get
= > y = – 3
Substitute the y value in equation (1), we get
2x – 3 * (-3) = -1
2x = -10
= > x = -5
By solving the equation (1) and (2), we get,
x = -5, y = -3
Hence, x < y
19) Answer: E
x2 + 13x + 40 = 0
x2 + 8x + 5x + 40 = 0
x(x + 8) + 5(x + 8) = 0
(x + 5)(x + 8) = 0
x = -5, -8
y2 – 7y – 60 = 0
y2 – 12y + 5y – 60 = 0
y(y – 12) + 5(y – 12) = 0
(y + 5)(y – 12) = 0
y = -5, 12
Hence, x ≤ y
20) Answer: D
2x + 2y = 30 ——–(1)
2x + y = 22 ———-(2)
(1) – (2)
y = 8
2x = 22 – 8 = 14
x = 7
Hence x < y
