What two numbers add to give you 4 and multiply to give you thirty?

The two numbers you are looking for are 10 and -6. They add up to 4 (10 + -6 = 4) and multiply to give you 30 (10 * -6 = -60). However, since the multiplication result should be positive, the correct numbers are 6 and -5, which add up to 1 but multiply to -30. Therefore, the equation needs to be corrected, as no two real numbers exist that meet the original conditions of adding to 4 and multiplying to 30.
