Question

Factorize the above expression

Answer 1

PLEASE MARK IT AS BRAINLEST ,

x4 – 3x - 2  has one root between 1 and 2 and one root between 0 and

 -1.(if your question is right) else

Please check your question x4 – 3x + 2  instead of x4 – 3x – 2. 

Here i will take positive in meddle term

So equation is x^4+3x+2.

Here there are four methods for finding solution of this polynomial.

We using NEWTOWN RAPSON method .

For this method first we find nearest value of the given equation .

Here f(x)=x^4+3x+2

Find value for f(x) lies between positive and negative value.

f(-0.7)=(-0.7)^4+3(-0.7)+2 =0.1401

f(-0.8)=(-0.8)^4+3(-0.8)+2=0.0096

f(-0.9)=(-0.9)^4+3(-0.9)+2= -0.0439

Here answer is lies between -0.9 to -0.8

f'(x)=4x^3+3

Take x= -0.8 (also you can calculate using take x=-0.9)
