Answer:

I think the question is mistyping or wrong

Explanation:

A+B=16

A*B = -80

Convert to

A=16-B

Substitute

(16-B)*B=-80

16B-B^2+80=0

Change the sign to make it easier (multiply by negative number)

B^2 -16B-80

=(B - 4)(B + 20)

B1=-4 and B2=20

Then its match if the product is -80.

Or second option is, assuming that the sum is 18, not 16

The A would be 8 and the B would be 10
