Question

Answer 1

1*30
2*15
3*10
5*6
Nothing.

Answer 2

A) x * y = 30
B) x + y = -12

x = 30/y

30/y + y = -12
30 + y² = -12y
y² +12y +30 = 0
y = -3.5505
y = -8.4495

B) x -3.5505 = -12
x = -8.4495

x -8.4495 = -12
x = -3.5505

y = -3.5505 and x = -8.4495
-3.5505 -8.4495 = -12

-3.5505 * -8.4495 = 30
