Answer:
x⁴ + 2 x² + 1
Step-by-step explanation:
given solution of the polynomial
i, −i, 1, −1.
equation of the polynomial will be equal to
=(x - i)(x + i)(x - 1)(x + 1)
= (x² + i x - i x - i²)(x² + x - x + 1)
=(x² - (-1))(x² + 1 )
= (x² + 1)(x² + 1)
= x⁴ + x² + x² + 1
= x⁴ + 2 x² + 1
hence, the required polynomial equation is x⁴ + 2 x² + 1
Answer:

Step-by-step explanation:
Hey there!!
Let angle 2 be x then,
measure of angle 1 is three less than twice of angle 2 = 2x-3.
Now, we have.
Measure of supplementary angle is 180°.
Angle 1 + angle 2 = 180°
x+(2x - 3)= 180°
3x -3=180°
3x= 180°+3°
Therefore, x = 61°.
Now, angle 2 = 61°
angle 1 = (61×2-3)= 119°.
check (119°+61°=180°).

So if you divide 78 by six you get 13. 78/6=13
So we want x minus 6 to equal thirteen we have to make x a number that will equal 13 when we subtract 6. So we can just add 13+6 to get 19. And 19-6=13. So x=19, does that make sense?
