Drag numbers into the blanks to show that f(x) = x - 2x + 5 has exactly 2 roots in the set of complex numbers by completing the square. x² - 2x+5=0
2-2x =
x² - 2x+
(x - 1)2 =
(x - 1) = +
Therefore, there are two roots of f(x), x =
and x =
-5
-4
-3
-2
- 1
0
1
2
3
4
5
21
1 + 2
1 -2i
-1 + 2i
-1-2i

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

the correct answers i think are b. and d.

give me brainliest if it is correct!

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

should have been evaluated with one odd value and one even value. the expressions have equivalent values when . when , the first expression has a value of 3 and the second
