Question

fx=4x³-12x²+11x-3. gx=x+1/2
Find the remainder ​

Answer 1

Step-by-step explanation:

g(x)=x+1/2=0

               x=-1/2

by the remainder theorem,remainder will be f(-1/2)

f(x)=4x^3-12x²+11x-3

f(-1/2)=4(-1/2)^3-12(-1/2)²+11*-1/2-3

        =4*-1/8-12*1/4-11/2-3

        =-1/2-3-11/2-3

        =-1-6-11-6/2

        =-24/2

        =-12 ans
