im in a review section in my class. this is some stuff i havent done in yrs. so if you could help with these 2 problems thatd be great (if possible, can you explain how you got the answer? i really dont remember this from that far back). . .

1. Find the value of K such that the quadratic equation x^2+(2K+1)x-(K/4) = 0 has only one solution

2.Determine the value(s) of x that makes the following statement true: 6x^(4/3) + 7x(2/3) = 3

plz & thank you
