Answer:

-6/5 (This is Answer c)

Explanation:

Re-writing this equation in standard form, we get:

25x^2 + 60x + 36 = 0. The coefficients are a = 25, b = 60 and c = 36.

The discriminant, b^2 - 4ac, is 60^2 - 4(25)(36), or 3600 - 3600, or 0.

Because the discriminant is 0, we have two real, equal roots, corresponding to

-b -60

x = ------ = ---------- = -6/5 (This is Answer c)

2a 2(25)
