If we apply the quadratic formula and find that the value of b^2 - 4ac equals zero, what can we conclude about the solutions?
A) The equation has no real number solutions.
B) The equation has exactly one irrational solution.
C) The equation has two different rational solutions
D) The equation has exactly one rational solution.
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-b+%2B-+0%29%2F%282%2Aa%29+
X=-B/2A......
The equation has exactly one rational solution.

D IS THE ANSWER..
