Question 609128: Help please!
Instructions: Use the quadratic formula to solve the equation
2x^2-x=-7
My answer is 1+i√55/4, 1-i√55/4.
Is this in the correct form or it should be 1+√55/4, 1-√55/4 and on the side the i?
Thanks

Hi

2x^2-x=-7 

2x^2-x+7=0

x+=+%281+%2B-+sqrt%28+55%29%29%2F%284%29+ 

  +x+=+1%2F4+%2B-+sqrt%2855%29%2F4   ||... 4 is under the entire Numerator

good to see You are concerned about the format to use: My first concern

would be if the radical is allowed in the answer, if so...

 x = 1/4 +√55/4 , 1/4 -√55/4  should work
