Explanation

let f(p) = 6p3 - p2 - 47p +30then by the remainder theorem,(p-3):f(3) = remainder Ri.e. f(3) = 6(3)3 - (3)2 -47(30 +30 =R 162 - 9 - 141 +30 = R 192 - 150 = Rtherefore R = 42To find the remainder when 6p - p² - 47p + 30 is divided by p - 3, we can use polynomial long division.Let's perform the division:```            6      ___________p - 3 | -p² - 47p + 6p + 30        p² - 3p        ___________              -44p + 30```The remainder is -44p + 30.Therefore, the remainder when 6p - p² - 47p + 30 is divided by p - 3 is -44p + 30.
