Follow FOIL Rule. Firsl solve the brackets. So 289/17 is 17 and squeare of 17 is 289. then solve the second bracket. Cube of -15 which is euivalent to -3375. But in the expression there is a minus sign before cube of (-15). So this will result in positive 3375. So, now we get the expression as 289+3375+2185 which is quivalent to 5849. Answer is 5849. Hope it is useful.
