Question

I will give a medal. Please explain how to do it not just the answer, thanks!

Solve x^2 - 3x = -8.

Answer 1

HI!!

Answer 2

Hello.

Answer 3

add 8 and solve
\[x^2-3x+8=0\] using the quadratic formula
\[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\] with
\[a=1,b=-3,c=8\]
there will be no real solutions, but two complex ones

Answer 4

So would \[x=3+-i \sqrt{23}/2\] be correct?

Answer 6

yes, but the real part is 3/2, not just 3
