i can help with a littel bit of it

Explanation:

1. answer

29±95‾‾‾√9

x

=

=−0.222222+1.08298

x

=

0.222222

+

1.08298

i

=−0.222222−1.08298

x

=

=−4±16−396‾‾‾‾‾‾‾‾‾√18

x

=

=−4±−380‾‾‾‾‾√18

x

=

4

±

18

The discriminant 2−4<0

b

2

4

a

c

<

0

so, there are two complex roots.

Simplify the Radical:

=−4±295‾‾‾√18

x

Simplify fractions and/or signs:

=−29±95‾‾‾√9

x

=

which becomes

=−0.222222+1.08298

x

=

0.222222

+

1.08298

i

=−0.222222−1.08298

2. Answer:

=−38±895‾‾‾‾√40

x

=

=−0.375+0.747914

x

=

i

=−0.375−0.747914

x

=
