Answer 2

SOLVE THE QUADRATIC EQUATION

Answer:

`x = 1 + √(7) i \\ x = 1 - √(7) i`

Step-by-step explanation:

`x {}^(2) - 2x + 8 = 0`

`(x - 1) {}^(2) + 8 - 1 {}^(2) = 0`

`(x - 1) {}^(2) = 8 - 1 {}^(2) = 0`

`(x - 1) {}^(2) = - 8 + 1 {}^(2)`

`(x - 1) {}^(2) = - 8 + 1`

`(x - 1) {}^(2) = - 7`

x - 1 = ± √-7

x = ±√7i + 1

`x = 1 + √(7) i \\ x = 1 - √(7) i`
