Question

If f(x)=x³+x²+3x+1 find the remainder when f(x) is divided by (x+2)

Answer 1

Step-by-step explanation:

remainder of given f(x) is -9

Answer 2

Answer:

$f(x) = {x}^{3} + {x}^{2} + 3x + 1$

$divided \: by \: (x + 2)$

$means \: if \: (x + 2) = 0$

$x = - 2$

$f( - 2) = remainder$

$remainder = { (- 2)}^{3} + {( - 2)}^{2} + 3( - 2) + 1$

$remainder = - 8 + 4 - 6 + 1 = - 9$
