Question

find the value of A and B so that the polynomial X cube + 10x square +ax + b is exactly divisible by X -1 as well as X -2

Answer 1

in this you have to divide the polynomial by x-1 and x-2 .then the what will the remainder come in both cases put both equal to 0. and then you will get two equations in A anb B variable . you will get A= -13 and B= 2

Answer 2

p(x)= X cube +10x square + ax + b
