Question

Two numbers multiply together to give -30 and add together to give -1.

What are the two numbers?

Answer 1

5, -6

Explanation:

We just need to find out the factors of -30 and they are 1 x -30, 2 x -15, 3 x 10 and 5 x -6. We can try out every factor to add so it's either:

-29

-13

-7

-1

the last is the answer we're looking for so it's 5 x -6

The 2 numbers are 5 and -6

Answer 2

-6 and 5
a minus and a positive make a minus
