Find the value of the discriminant. Describe the number and type of roots. 4x^2 - 6x + 2 =0 I tried it at least, and I got 4 for the discriminant... That's all I know, and I don't even know if it's right. So please, help me.. I suck at math

    \(\huge\color{reD}{\rm b^2-4ac}\) `Discriminant` you can use this to find if the equation is factorable or not if ` b^2-4ac > 0` then there are 2 real zeros if ` b^2-4ac = 0` then there is one real root if ` b^2-4ac < 0` then you will get two complex roots (no -x-intercept)

    Ok, so i did do that, and i got four for the discriminant. Does that mean that the root is 2, and that it is a complex root?

    4 is greater than or less than 0 ?

    Um.. I think...? I'm very unsure about math. It is not my forte. I just got very confused..

    so 4 is greater than 0 right ? 4 is bigger than 0 ?

    if b^2-4ac> 0 then how many roots would you have ?

    yes right if you get positive number then you get 2 solutions

    remember if discriminant = 0 then one solution if discriminant is a negative number then no real solution and if discriminant is positive number then 2 solutions

    ohh, that makes sense! I never learned anything about roots. so since its positive, it will have 2 solutions, in other words, 2 roots. correct?
