Consider only the discriminant, b2  4ac, to determine whether one realnumber solution, two different realnumber solutions, or two different imaginarynumber solutions. 2x2 = 2 5
Thank you

Are you missing an x?
2x^2 + 2x + 5 = 0
a = 2
b=2
c = 5
If your answer = 0 then there is only 1 real number solution.
If your answer = any positive number you will have two real solutions
If your answer = any negative number you will have two imaginary solutions.
All of the above happens because in the quadratic equation you take +/ the square root of b^24ac
