Question

Which of the following is a solution of x2 - 6x = -10?

x = -3 - i

x = 3 + i

x equals 3 plus i times the square root of 19

x equals negative 3 minus i times the square root of 19

Answer 1

x = 3 + i ^_^ http://www.wolframalpha.com/input/?i=x%5E2+-+6x+%3D+-10 :D

Answer 2

\[x2 - 6x = -10\]\[x2 - 6x + 10 = -10 +10\]\[x^2 - 6x +10=0\]
Which methods to solve this do you know?

Answer 3

Factoring
Quadratic formula
Completing the square

Answer 4

\[x^2 - 6x+ 10=0\]\[(x-3)^2=-1\]technically\[x=±i+3\]so\[x=i+3\]
