Question

solve x2+2x-2=0 by formulated method​

Answer 1

Answer:

$a = 1 \: . \: b = 2. \: c = - 2$

$Δ = {b}^{2} - 4ac$

$= - 4 - 8$

$= - 4$

$since \: Δ$

< 0 the equation has no solutions.

$x = \frac{ - 2 + \sqrt{ - 4} }{2}$

$= \: \frac{ - 2 + 2i}{2}$

$=> x = - 1 + i$

Mark me as brainliest....

Answer 2

Step-by-step explanation:

x = -1 +2i OR x= -1 - 2i
