(A) For what value of K does the equation 2x^2-10x +8 = K have a repeated root? Use the quadratic formula to find the root.
(B) Choose a value for K so the equation has no real roots, Use the quadratic formula to prove that this equation has no real roots for your chosen value for K.
this is a question i was given and to be honest i am stumped, i understand what a root is, but im unsure of how to find a repeated root. any help is appreciated!
