A quadratic equation only has one solution when thediscriminantis equal to zero.

Note that the discriminant is defined by

Since our quadratic equation has the form , we see that the discriminant then would be

Set this equal to zero and solve for K.

Can you try to take it from here?

With a little rearrangement, we see that this equation can be written as2.Determine the value(s) of x that makes the following statement true: 6x^(4/3) + 7x(2/3) = 3

plz & thank you

Now make a little substitution: let's say

Then this becomes a quadratic equation:

Solve this equation, and then back substitute to solve for x.

Can you try to take it from here?

Does this make sense?
