Determine the number of real number solutions from the giving graph of 5X squared plus 4X +9 equals zero how many real number solutions are there?

Answer 1

You did not provide a graph to examine, but you can answer the question by evaluating the discriminant D.

D = 0 ⇒ 1 real solution, multiplicity of 2

D > 0 ⇒ 2 distinct real solutions

D < 0 ⇒ 2 distinct complex solutions
