Question

Find the remainder when x3+x+1 is divided by x+2​

Answer 1

$\huge \green{x - a = x + 2} \\ \huge \green{a = - 2}$

$\huge \red{ p(x) = 3x + x + 1} \\\huge \red{ p( - 2) = 3( - 2) - 2 + 1 } \\ \huge \red{ = - 6 - 2 +1}\\ \huge \red{ - 8 + 1 } \\ \huge \red{ - 7}$

hope it's my answer and please follow me
