To find two factors of 32 that add up to -12, we need to solve a system of equations. Let's denote the two factors as x and y. We have the equations x * y = 32 and x + y = -12. By substituting y = -12 - x into the first equation, we get x * (-12 - x) = 32. Solving this quadratic equation, we find the factors to be -8 and -4.

First, add two plus ten together. That number is 12. Then do the opposite function that you did earlier, which would be multiplying by 3. 12 times 3 is 36, so the answer is 36.

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.
