Question 132946: Determine whether the following equations have a solution or not? Justify your answer.
(7)1/2y2 - 6y - 13(7)1/2 = 0 Please help with this difficult question.
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
(7)1/2y^2 - 6y - 13(7)1/2 = 0
Multiply thru by 2 to get rid of the fractions:
7y^2 -12y -91 = 0
y = [12 +-sqrt(12^2-4*7*-91)]/14
y = [12 +- 51.8845]/14
y = 4.5632... or y = -2.8489..
