root. Determine all values of the real parameter K so that the equation has at least one real (a) x+(3k7)x + 2k+6=0 (b) kx2+8x+k-6=0
root. Determine all values of the real parameter K so that the equation has at least one real (a) x+(3k7)x + 2k+6=0 (b) kx2+8x+k-6=0 #2. Determine the largest value of y for which the equation has a real solution. x+ xy + y = 1 x - (2a + 1)x+a+2=0 #3. Determine all parameters a R so that the equation has one root twice as large as the other.
