According to Wolfram Alpha, (1/2) (9 plus or minus i times the square root of 39)
Since these numbers are complex, it means there is no solution with real numbers for this problem.
The two numbers are 5 and -6. 5x(-6) = -30 so the product is -30 and 5+(-6) = -1 so the sum is -1
The numbers are 5 and 6.
10 and 3
You need two numbers whose sum is -1 and whose product is -30. The numbers are -6 and 5 So x2 -x - 30 = x2 - 6x + 5x - 30 = x(x - 6) + 5(x - 6) = (x - 6)(x + 5)
The numbers are -30, -28 and -26.
How about: 30 and 30

10 and 20.
15 and 2
The two numbers are 5 and -6. 5x(-6) = -30 so the product is -30 and 5+(-6) = -1 so the sum is -1
The numbers are 5 and 6.

30 and 70 Check: 30+70 = 100 and 30*70 = 2100
seven and eight
17 & 13
278
Take 13 and 17 as an example. Sum is 13 + 17 ie 30, product is 13 x 17 = 221
