Question

Give all solutions to the following non-linear system of equations.
y = x 2 − 4
y = − x 2 + 5

Answer 1

is that 2x or x^2?

Answer 2

x^2

Answer 3

so sorry about that reply

Answer 4

I thought it was a good reply why did you delete it?

Answer 5

y? y it gone

Answer 6

sorry there are only 2 answers and I screwed up

Answer 7

try it again

Answer 8

sorry about that
so by addition you get
\[2y=1\]
thus \[y=1/2\]
There are two answers since both equations have a high power of 2
so y=1/2 and y=1/2
now both equations are \[x=9/2\]
so
\[x=3\sqrt{2}/2\]
and
\[x=-3\sqrt{2}/2\]
so the answers are (\[3\sqrt{2}/2\],1)
and
(\[-3\sqrt{2}/2\],1)
there's your answer, sorry the formatting is screwed up

Answer 9
