Question

quick question for everyone! What two numbers add up to 1, but when multiplied equal -3?

Answer 1

*id also like to know how you solved it

Answer 2

we can start with two variables \(x\) and \(y\)

Answer 3

they add to 1 so \(x+y=1\)
they multiply to give \(-3\) so \(xy=-3\)

Answer 4

to make one variable out of this mess, \(x+y=1\) is the same as \(y=1-x\)
put that in the second equation and get
\[x(1-x)=-3\]

Answer 5

then solve that one

Answer 6

you good from there?

Answer 7

nope haha ive been out of school for a long time, i only come here to help friends usually

Answer 8

\[x(1-x)=-3\\
x-x^2=-3\\
x^2-x-3=0\] then use the quadratic formula to solve it

Answer 9

im working it for now
