Answers :

Directions (1-5) :

1) Answer: e)

I) x2 – 3x – 28 = 0

(x + 4) (x – 7) = 0

X = -4, 7

II) y2 – y – 72 = 0

(y + 8) (y – 9) = 0

Y = -8, 9

Can’t be determined

2) Answer: e)

I) 3x2 + 19x + 28 = 0

3x2 + 12x + 7x + 28 = 0

3x (x + 4) + 7 (x + 4) = 0

(3x + 7) (x + 4) = 0

x = -7/3, -4 = -2.33, – 4

II) 2y2 + 13y + 21 = 0

2y2 + 6y + 7y + 21 = 0

2y (y + 3) + 7 (y + 3) = 0

(2y + 7) (y + 3) = 0

y = -7/2, -3 = -3.5, -3

Can’t be determined

3) Answer: c)

2x-3y = -6 –> (1)

3x + 4y = 25 –> (2)

By solving the equation (1) and (2),

x = 3, y = 4

x < y

4) Answer: a)

I) 12x2 – 37x + 21 = 0

12x2 – 28x – 9x + 21 = 0

4x (3x – 7) – 3 (3x – 7) = 0

(4x – 3) (3x – 7) = 0

x = ¾, 7/3 = 0.75, 2.33

II) 15y2 + 54y + 27 = 0

15y2 + 45y+ 9y + 27 = 0

15y (y + 3) + 9 (y + 3) = 0

(15y + 9) (y + 3) = 0

y = -9/15, -3 = -3/5, -3

x > y

5) Answer: e)

I) x2 + 3√7 x – 70 = 0

x2 + 5√7 x – 2√7 x – 70 = 0

(x + 5√7) (x – 2√7) = 0

x = 2√7, – 5√7

II) y2 + 2√3 y – 105 = 0

y2 + 7√3 y – 5√3 y – 105 = 0

(y + 7√3) (y – 5√3) = 0

y = 5√3, – 7√3

Can’t be determined
