IF YOU SOLVE I WILL BE YOUR BEST FRIEND I SWEAR. ALSO WILL AWARD THE BRAINLIEST THING. PLEASE. I NEED THESE GRADES SO I WONT BE A DISSAPOINTMENT TO MY MY MOM!

Step-by-step explanation:

x⁵ - 8x⁴ + 22x³ - 26x² + 21x - 18 = 0

x = 2,  x = ± i,   x=3  with multiplicity 2

x⁴ - 5x³ + 7x² - 5x + 6 = 0

x = 2,   x=3,   x = ± i

-1 + 4i    =  4 + i

    i

x³ - 26x² + 21x - 18 = 0

x = ± 2i,   x = 3/2

(1 + i) (-3 - 4i)

= 1 - 7i

6.

(-5 + 2i) + (3 - 6i)

= -2 -4i

7.

x⁴ + 5x² + 4 = 0

x = ± i ,     x = ± 2i

8.

(7 - i) - (-5 + 6i)

= 12 - 7i

9.

(4 - i) (4 + i)

= 17

10.

(3 + 8i) (4 - 3i)

= 36 + 23i

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
