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
Answer:
x = (1 + root (-79)) / 8
x = (1 - root (-79)) / 8
