Question

HELP?

so I'm factoring trinomials and so far, I've got the answers, but I'm having a tough time figuring out which two numbers added together will get -20 while as those two numbers were multiplied together will get -1. Thank you! x

Answer 1

x + y = -20

x*y = -1

x = -20 -y

-20y - y^2 = 1

y^2 +20y + 1 =0

y = -0.05 and x = -19.95 or vice versa
