Here is the question 3x^2-24x+48=0, determine the value of the discriminant. What does this value tell you about the equation? How many times does the corresponding function cross the x-axis?(adsbygoogle = window.adsbygoogle || []).push({});

Ok first part a=3 b=-24 c=48

discriminant b^2-4ac

so (-24)^2-4(3)(48)

576-576=0

So first question what does the value tell u about the equation? Would it be right to say that the value 0 tells us that the equation has one double root?

And for the second question? Well would it be right to say that the function doesn't cross the axis at all? Or well it could have crossed twice if the double root was negative, but if its a root then it cant be in the middle it must be on the x-axis?
