I believe you need to solve this using the quadratic formula!
To begin, this is what it is:
x= -b ± <span>√ b^2 - 4ac / 2a
Just plug in what you have in your problem...
2 being a, 13 being b, and -24 being c.
So we get:
x= -13 </span>± <span>√13^2 - 4(2)(-24) / 2(2)
x= -13 </span><span>± √169 - 8 (-24) / 4</span>
<span>x= -13 <span>± √169 + 192 / 4</span>
x= -13 </span>± √<span>361 / 4
The square root of 361 is 19.
So you have: -13 </span><span>± 19 / 4.
Here's where you take the equation </span>-13 <span>± 19 and put the addition and subtraction sign to use.
-13 - 19 = -32
and
-13 + 19 = 6
Now all is left to do is divide the two numbers by 4.
-32/4 = -8
and
6/4 = 3/2
x = -8, 3/2</span>
The imaginary unit, i, which represents the square root of -1 raised to power 4 is 1
The organized steps are;
- Choice F; Therefore, Sebastian is incorrect
Reason:
The given expression Sebastian simplified is; -4·i²¹²
The result Sebastian got = 4
The organized steps are presented as follows;
We have that 212 ÷ 4 = 3
Since i⁴ = 1
Then -4·1 = -4
Therefore, Sebastian is incorrect
The order of the steps are therefore;
Given -4·i²¹²
Choice E; Since i⁴ = 1
Choice B; Then -4·1 = -4
Choice F; Therefore, Sebastian is incorrect

Answer: System 1 has an infinite number of solutions and System II has no solutions.
Step-by-step explanation:
If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.
If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.
