Question

What two numbers multiply to 36 and add up to -20?

Answer 1

Answer:

  -2 and -18

Step-by-step explanation:

It is useful to consider the factors of 36:

  36 = (-1)(-36) = (-2)(-18) = (-3)(-12) = (-4)(-9) = (-6)(-6)

The sums of these factor pairs are -37, -20, -15, -13, -12.

The factor pair of interest is -2 and -18.
