Solution

1) Answer : E

I. x2 - 11x + 28 = 0,

II. 2y2 - 5y - 12 = 0

x = 7, 4

y= 4, -3/2

2) Answer: B

I. x2 + 12x + 35 = 0,

II. y2 + 7y + 10 = 0

=> x = -7, -5

=> y = -5, -2

3) Answer : A

I. x2 + 8x + 16 = 0,

II. y2 - 16y + 39 = 0

=> x = -4

=> y = 13, 3

4) Answers : C

I. x2 - 5x - 24 = 0,

II. y2 = 49

=> x = 8, -3

=> y = ± 7

5. Answer : C

I. x2 + 8x + 7 = 0,

II. y2 + 9y +18 = 0

=> x = -7, -1

=> y = -6, -3

6) Answer: a)

*2+1, *3+1, *4+1, *5+6, *6+1

7) Answer: a)
