Best ResponseYou've already chosen the best response.2You'll need them to calculate the discriminant, which in turn is necessary to find the number of real/complex roots.

Best ResponseYou've already chosen the best response.2The powers of x do not count, because it comes from ax^2+bx+c, so a,b,c do not contain the powers of x, just the coefficients will do.

Best ResponseYou've already chosen the best response.2But you need to include the signs, so it is a=3, b=6 c=4

Best ResponseYou've already chosen the best response.2ok, you'll be needing this for you test or exam, so try to get familiar with it, if you can: discriminant = \(b^24ac\)

Best ResponseYou've already chosen the best response.2if the discriminant is negative, all roots are complex. If the discriminant is positive, there will be two distinct (different) real roots if the discriminant is zero, there will be two coincident (same value) real roots.
