Question

what two numbers, when multiplied, give a product of -160; yet when added, equal 6?

Answer 1

So let the two numbers be x and y.

Then
xy = -160
and
x + y = 6

From the second equation, we have that y = 6 - x

Substitute that now into the first equation and solve for x.

Answer 2

xy = -160

x + y = 6

Now evaluate y from one and put it into other to get x value..

Answer 3

Make sense?

Answer 4

Try with factors of -160..
8*(-20) --------- sum is not 6
10*(-16) -----------sum is not 6

16*(-10)

Yes this produces -160 and sum = 16 - 10 = 6
