2 {x}^{3}  - 5 {x}^{2}  + x + 2 = 0
2 {x}^{3}  - 4 {x}^{2}  -  {x}^{2}  + 2x - x + 2 = 0
2 {x}^{2} (x - 2) - x(x - 2) - (x - 2) = 0
(x - 2)(2 {x}^{2}  - x - 1) = 0
(x - 2)(2 {x}^{2}  - 2x + x - 1) = 0
(x - 2)(x - 1)(2x + 1) = 0
x = 2
x =  1
x =  - 0.5

Please solve these. Will rate you 5 star! ​

Answer: Hi!

To find the answer for question 24, we would first find the square root of 20 and 5. The square root of 20 is about 4.47 (I used a calculator for convenience) and the square root of 5 is about 2.24. Now we need to add these:

4.47 + 2.24 = 6.71

Now we divide 30 by this:

30/6.71 = 4.47

Now, we'll evaluate the answer choices.

a) is equal to 1.49

b) is equal to 13.4

c) is equal to 4.47

d) is equal to 26.88

The answer choice that is correct is c, because it is what we got for the problem that we were supposed to solve in the beginning.

Hope this helps!
