x^2 - x/5 + 2 = 0
Subtract 2 from both sides.
x^2 - x/5 = -2
Multiply all terms by 5.
5x^2 - x = -10
Add 10 to both sides.
5x^2 - x + 10 = 0
We can now apply the quadratic formula:
1 ± (√ 1 - 200) / 10
1 ± √-199 / 10
1 ± i√199 / 10
<h3><u>The solutions are equal to 1 + or - i times the square root of 199 divided by 10.</u></h3>
Answer:
Pretty sure it is C
Step-by-step explanation:
![x \leq -2\\ (- \alpha ,-2]](https://tex.z-dn.net/?f=x%20%20%5Cleq%20-2%5C%5C%0A%28-%20%5Calpha%20%2C-2%5D%20)
Note: the infinity character would not render correctly, so I used alpha instead. Pretend it's an infinity sign.
