Question

use the discriminant to determine the number of solutions of the quadratic equation, and whether the solutions are real or complex. Note: It is not necessary to find the roots; just determine the number and types of solutions
(3)^1/2 y^2 - 4y - 7(3)^1/2 = 0

Answer 1

Hmm... \[\Delta = b^2 -4ac\] Δ > 0 => 2 distinct real roots
Δ = 0 => 1 double real root
Δ <0 => 2 distinct complex roots
