Question 849698: Use the discriminant to determine whether the following equation has solutions that are two different rational solutions, two different irrational solutions; exactly one rational solution; or two different imaginary solutions.y2 + 7y + 1 = 0

a =1 b =7 c = 1
Let D be our discriminant and let D = b^2-4ac (the expression that is under the quadratic formula's square root)
7^2 - 4*1*1 = 45 > 0
So we have two real solutions.
