Question

verify the division algorithm for the polynomials p(x)= x³+x²+2x+3 and g(x)=x+2 Find p(-2). What do you observe?​

Answer 1

Answer:

p(-2)=-5

Step-by-step explanation:

Given

p(x)= x3+x2+2x+3

g(x)=x+2

Therefore,

Zero of p(x)= -2

By remainders theorem

p(-2)= (-2)•(-2)•(-2)+(-2)•(-2)+2(-2)+3

-8+4-4+3

-5
