Best ResponseYou've already chosen the best response.0Well, the textbook definition is "the discriminant is the expression under the radical sign in the quadratic formula."

Best ResponseYou've already chosen the best response.0From the quadratic formula.. \[\large \frac{b \pm \color\red{\sqrt{b^2  4ac}}}{2a}\] The red is your descriminant

Best ResponseYou've already chosen the best response.0So from your equation \[\large 3x^25x + 4 = 0\] A,B and C are the coefficients of the quadratic 3 = A 5 = B 4 = C so we plug those into the discriminant and what do we get?
