Can you please help me with this maths question 1. Let P(x) = (x+1)(x-3)Q(x)+a(x+1)+b , where Q(x) is a polynomial and a and b are real numbers When P(x) is divided by (x+1) the remainder is -11. When P(x) is divided by (x-3) the remainder is 1. (i) What is the value of b? (ii) What is the remainder when P(x) is divided by (x+1)(x-3) ?

    p(3)=4a+b b=-11 and R=1 1=4a-11 4a=12 a=3
