Answer 2

Answer:

a x^2 - 6 x - 6 = 0

x = (6 +- (36 + 24 a)^1/2) / (2 a)    quadratic formula

(36 - 36 + 24 a) / (4 a^2) = 4       since (a - b) * (a + b) = a^2 - b^2

24 a = 16 a^2         so a = 1.5

Check:   1.5 x^2 - 6 x - 6 = 0

(6 +- (36 + 36)^1/2) / 3 = x

(2 +- 2 * 2^1/2 = x = (4.828, -.8285)

4.828 * -.8285 = 4
