Find the remainder when f(x)=−2x3+x2−4x+1 is divided by x+3.
harina [27]

The remainder when f(x)=−2x3+x2−4x+1 is divided by x+3. is 76

<h3>How to determine the remainder?</h3>

The function is given as:

f(x)=−2x3+x2−4x+1 is divided by x+3.

Set the divisor to 0

x + 3 = 0

Solve for x

x = -3

Calculate f(-3)

f(-3)=−2(-3)^3+(-3)^2 − 4(-3) + 1

Evaluate the expression

f(-3)= 76

Hence, the remainder when f(x)=−2x3+x2−4x+1 is divided by x+3. is 76
