Question

find the remainder by remainder theorem when x^3 +2x^2 + 2x + 1 is divided by x + 2

Answer 1

Answer:

  ⇒ By  putting the value method,

  ⇒  g(x) = x+2

  ⇒         = x +2 = 0

  ⇒         = x = 0 - 2

  ⇒  p(x) =  x = -2

Step-by-step explanation:

= p(x) = x³+2x²+2x+1

=          (-2)³ + 2(-2)²+ 2(-2) + 1

=          -8 + 4 - 4 + 1

=   p(x)  =  -7
