## ashlynxo one year ago Use the discriminant to find the number of real solutions of the equation 3x^2 – 5x + 4 = 0. Show your work.

I forgot what is discriminant of a quadratic. Do you remember?

From the quadratic formula.. $\large \frac{-b \pm \color\red{\sqrt{b^2 - 4ac}}}{2a}$ The red is your descriminant

So from your equation $\large 3x^2-5x + 4 = 0$ 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?
