Question

please answer with steps​

Answer 1

Answer:

D. 2x^3-4x^2-5x+1

Step-by-step explanation:

If (x+1) is a factor if any polynomial , then

sum of coefficient of odd power of x and sum of coefficient of even power of x will be equal.

That means ,

for odd power of x ,

sum of coeff. = 2 - 5 = -3

and for even power of x ,

sum of coeff. = - 4 + 1 = -3.

so,

right answer is D.

Answer 2

(d) 2x³–4x²–5x+1 is right answer.

you need to put the value of x+1=O. =}x=-1 in every factor given below
