a) Show that 2x-1 is a factor of the polynomial 2x³ - 3x² - 11x + 6

Find the other factors of the polynomial

b) Find, correct to three decimal places, the values of t satisfying

2e^3t - 3e^2t - 11e^t + 6 = 0

Could someone hellp me start this question because I've no idea at all what to do. If someone could start me off i might be able to figure it out.

thanks
