Hi,

Re TY: In this case, discriminant is = 0 ⇒ one real solution,  x = 3/4

4/3x^2 - 2x + 3/4 = 0  ||standard format ax^2 + bx + c = 0



The Discriminant test

 



If discriminant is = 0 ⇒ one real solution, in this case x = 3/4

If discriminant is > 0 ⇒ two real solutions

If discriminant is < 0 ⇒ two complex solutions
