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
is written as ix (
)
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)
