Question

What times what equals -120 and adds up to 14

Answer 1

you can solve it with the following method:
a+b=14
a=14-b
axb=-120
(14-b)b=-120 (replace the a value in terms of b found in the last step)
-b²+14b=-120
-b²+14b+120=0
using the quadratic equation you should get b= 20 and -6

Answer 2

Hello!,
-200 + 80 = -120 then

-120+134=14
