Since 30 is positive and the sum is negative, both factors must be negative. Let's just look for pairs of factors of 30:
30 = 1x30 = 2x15 = 3x10 = 5x6.
None of these factor pairs add to 30, so you can't solve this over the integers.
You are probably trying to solve a quadratic equation like x2 -12x +30 = 0. Since you can't find two binomial factors for the trinomial, you will have to use the quadratic formula to solve the equation. Haven't got that far in your algebra class? OK, just say it can't be done.
They are: -3 and 4
2.536 and 9.464 (to 3 dp)
Product = 35 Sum = 12
The sum of all the positive factors of 12 is 28.
6 and 2 are a number pair with a sum of 8 and a product of 12
They are: -3 and 4
There are no such numbers. The only two numbers that sum to 12 and whose product is -84 are irrational, and so cannot be considered as factors of 84.
2.536 and 9.464 (to 3 dp)
The integers 2 and 10 have a product of 20 and a sum of 12.
Product = 35 Sum = 12
The sum of 72 and 12 is 84. The product of the two numbers is 864.
