In this case it is to find the roots of the polynomial.
We have then:
2x ^ 2-5x + 1 = 3
Rewriting:
2x ^ 2-5x-2 = 0
Applying resolver we have
x = (- b +/- root (b ^ 2 - 4ac)) / (2a)
Substituting values:
x = (- (- 5) +/- root ((- 5) ^ 2 - 4 (2) (- 2))) / (2 (2))
x = (- (- 5) +/- root ((25 + 16)) / (2 (2))
x = (5 +/- root (41))) / (4)
x = ((5/4) +/- (root (41)) / 4)
Answer:
x = ((5/4) +/- (root (41)) / 4)

Answer: f(x) is an odd function
Step-by-step explanation: The major characteristic of odd functions is that one end of the graph goes down to negative infinity, the other end goes up to positive infinity.
Answer:
8 units
Step-by-step explanation:
<u>Area of a rectangle</u> = <em>Width</em> multiplied by Length
Substitute in all the known numbers into this formula to get
<u>72</u> = <em>(9)</em> ×
Solve the equation for x, to find out the length
![9(2x+4)=72](https://tex.z-dn.net/?f=9%282x%2B4%29%3D72)
![2x+4=72/9](https://tex.z-dn.net/?f=2x%2B4%3D72%2F9)
![2x+4=8](https://tex.z-dn.net/?f=2x%2B4%3D8)
![2x=8-4](https://tex.z-dn.net/?f=2x%3D8-4)
![2x=4](https://tex.z-dn.net/?f=2x%3D4)
![x=4/2](https://tex.z-dn.net/?f=x%3D4%2F2)
![x=2](https://tex.z-dn.net/?f=x%3D2)
Length of the rectangle = ![(2x+4)](https://tex.z-dn.net/?f=%282x%2B4%29)
![2(2)+4](https://tex.z-dn.net/?f=2%282%29%2B4)
![4+4=8](https://tex.z-dn.net/?f=4%2B4%3D8)
18bags
Look if 1=3 2=9 3= 18 so he uses 18 bags!
