What is the solution?
1/2x2-x+5=0

So for this, I will be completing the square. Firstly, subtract 5 on both sides of the equation:

Next, multiply both sides by 2:

Next, we want to make the left side of the equation a perfect square. To find the constant of the soon-to-be perfect square, divide the x coefficient by 2 and then square the quotient. Add the result to both sides of the equation:

-2 ÷ 2 = -1, (-1)² = 1

Next, factor the left side:

Next, square root both sides of the equation:

Next, remember that i = √-1 so factor that out on the right side of the equation:

Lastly, add both sides by 1:

In short, your answer is , or the third option.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
