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.

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.
