Answer:

there are several methods to "solve a quadratic"

you can look them all up...

Graphing, factoring, completing the square, taking roots, quadratic formula are the common methods....

given the way you are asking the question I think that you are supposed to use the quadratic formula ..

please look at the image of the formula and

realize that you problem has

a=-1

b=2

c=6

just plug in those numbers into the formula and you will get the results in the "answer"

NOTE $\sqrt{-x}$ is written as ix ( $\sqrt{-25} = 5i$ )

Step-by-step explanation:

x= <u>-2+√ (2)²- (4)(-1)(-6) </u>

(2)(-1)

and

x= <u>-2-√ (2)²- (4)(-1)(-6) </u>

(2)(-1)
