If a, b, and c are consecutive Fibonacci numbers and a^2 + 4bc = 64, find a in terms of b and c.
Fibonacci numbers are numbers of the form: 1, 1, 2, 3, 5, 8, 13, 21, 34, x, y, x+y.............
Given: a^2 + 4bc = 64 for three specific Fibonacci numbers a, b, and c.
a^2 + 4bc = 64
Transposing terms we have:
a^2 = 64 - 4bc.
Taking the square root of both sides we have:
a = ?(64-4bc)
= (?4).?(16-bc) = 2?(16-bc).
Answer : a = 2?(16-bc)

I am very sorry that it took me much time to get back to this question after it was posted about two months ago.

If a, b, and c are consecutive Fibonacci numbers and a^2 + 4bc = 64, find the values a, b, and...c. Show your work.

Prove that for any four consecutive Fibonacci numbers a, b, c, d, the square root of a^2 + 4bc...is always a perfect square whose square root is equal to d.
