We can find the remainder simply by substituting the value of x
Given x³+3x²+4x+1 is divided by x+1
x+1 = 0
x = -1
Put x = -1 in x³+3x²+4x+1
» x³ + 3x² + 4x + 1
» (-1)³ + 3(-1)² + 4(-1) + 1
» -1 + 3(1) - 4 + 1
» -1 + 3 - 4 + 1
» -1
Therefore, the remainder when x³+3x²+4x+1 is divided by x+1 is "-1"
