Hey can you me posted picture of question

We have the following equation:
 4x2-x + 5 = 0
 Using the resolver we have:
 x = (- b +/- root (b2 - 4ac)) / 2a
 Substituting values we have:
 x = (- (- 1) +/- root ((- 1) 2 - 4 (4) (5))) / 2 (4)
 Rewriting:
 x = (1 +/- root (1 - 80)) / 8
 x = (1 +/- root (-79)) / 8
 The results are:
 x = (1 + root (-79)) / 8
 x = (1 - root (-79)) / 8
 
 x = (1 + root (-79)) / 8
 x = (1 - root (-79)) / 8
 C y E option
