Show that the polynomial does not have any rational zeros. P(x)=x²-x-5 We first determine all the possible rational zeros of P(x). (Enter your answers as a comma-separated list.) x= We find the lower bound to be x = and the largest x-value last.) 0 -1 and the upper bound to be x = -5 We now use synthetic division to test the values between the lower and upper bounds. (Work in ascending order. Test the smallest x-value fir
