For this case we have the following equation:
-2y2 + 6y = -2
Rewriting we have:
-2y2 + 6y + 2 = 0
Using the quadratic formula we have:
x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
Substituting values:
x = (- (6) +/- root ((6) ^ 2 - 4 * (- 2) * (2))) / (2 * (- 2))
Rewriting:
x = (- 6 +/- root (36 + 16)) / (- 4)
x = (- 6 +/- root (52)) / (- 4)
x = (- 6 +/- root (4 * 13)) / (- 4)
x = (- 6 +/- 2 * root (13)) / (- 4)
x = (- 3 +/- root (13)) / (- 2)
The roots are:
x1 = (- 3 - root (13)) / (- 2)
x2 = (- 3 + root (13)) / (- 2)
Rewriting:
x1 = -0.3
x2 = 3.3
Answer:
–0.3, 3.3
The length of ad would also have to be the three also. This is logically because ac and bd would be the two going across making them equal. This meaning to connect the lines together if they were parallel bc and ad lengths would be equivalent.
