The two numbers that add to give you 18 and multiply to give you 40 are 10 and 8. This is because 10 + 8 = 18 and 10 x 8 = 80. However, if the question is referring to two numbers that add to 18 and multiply to 40, the correct pair would be 5 and 8, as 5 + 8 = 13 and 5 x 8 = 40.

There are no two real numbers that do. Using complex numbers, these two do: (-3/2 + i√151/2) & (-3/2 - i√151/2) Two numbers that add to -3 and multiply to -40 are -8 & 5 Two numbers that add to 3 and multiply to -40 are 8 & -5 Two complex numbers that add to 3 and multiply to 40 are (3/2 + i√151/2) & (3/2 - i√151/2)
They are 40 and 40
