Sorry kid, I'm not here to do your homework for you. While I was able to answer it instantaneously, I won't give you the pleasure of knowing the answer for yourself.

>>35117710
This isn't about giving me the answer, it's about proving that you can do it to all your fellow robots.

6+-(5^0.5)j, -3+-(5^0.5)j

+- is plus/minus.
Why can't we use unicode here again?

They aren't whole numbers and I don't care enough to actually do math at 8am on a Saturday. Dropped.

Did you just learn quadratic equations in school and want to show off to all your imaginary internet friends that you understood it? I'm very confused.

There's 2 answers, as the first equation describes a line and the second describes a circle. If you can't solve this you might be retarded

>tfw i developed stockholm syndrome for math
I absolutely hated it but because of my class being more intelligent than the whole school we had to get advanced math instead of normal. I hated it at the start, now i love it, also your problem is easy as fuck op.

2x-y=15
y=2x-15
y^2=4x^2 -60x +225

x^2 + 4x^2 -60x + 225 = 20
5x^2 -60x +205 = 0
x^2 -12x + 41 = 0
x=6 +- 2.236

The line doesn't intersect with the circle in this case. If you were anything short of legally retarded, you would see that in an instant

>>35117675
I can't solve it, OP. You win.

>>35117773
Just because it doesn't really happen doesn't mean there isn't an imaginary answer.

x = 6 + i*sqrt(5)
y= i(2*sqrt(5) + 3i)

>>35117675
x^2 + (2x - 15)^2 = 20
x^2 + 4x^2 - 60x + 225 = 20
5x^2 - 60x + 205 = 0
x^2 - 12x + 41 = 0

(12 +/- sqrt(144 - 4 * 41)) / 2
(12 +/- sqrt(144 - 164) / 2
(12 +/- sqrt(-20)) / 2
(12 +/- 4.472i) / 2

I can't see where you're fucking it up.

He isn't, he just typo'd out the 'i' at the end

x = -5
y = 35

gives imaginary answers (non real)

>>35117675
Kid, I studied linear algebra. If you want help with your home work go here >>>/hm/

I got bad news for you, Anon

>>35117960
that's wrong
2 * -5 - 35 =/= 15

x1=3+sqrt(-32)
x2=3-sqrt(-32)

Well.

I'll take the bait.

X1 = 6+3i
X2 = 6-3i

>>35118354
and by extension y1/2 = -3 +- 6i
