Question

for the given polynomial P(x) and the given c, use the remainder theorem to fid P(c).

P(x)=x^3+3x^2-7x=4 ; c=1

Answer 1

P(x)=4? you sure thats supposed to = 4?

Answer 2

P(x)=x^3+3x^2-7x+4 ; c=1

Answer 3

find P(1) = (1)^3 + 3(1)^2 - 7(1) + 4

P(1) = -1

then when x^3 + 3x^2 -7x +4 is divided by (x -1) the remainder is -1

Answer 4

1 3 -7 4
0 1 4 -3
1 4 -3 1
therefore P(1) is 1 for P(1)
