How to factorise x+x3​
serious [3.7K]

Answer: x • (x^2 + 1)

Find roots (zeroes) of :       F(x) = x2 + 1

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  1  and the Trailing Constant is  1.

The factor(s) are:

of the Leading Coefficient :  1

of the Trailing Constant :  1

Let us test ....

  P    Q    P/Q    F(P/Q)     Divisor

     -1       1        -1.00        2.00      

     1       1        1.00        2.00

Help Please. Can't seem to understand how to do this. I have tried and watch over 5 videos. Can't seem to get it.​
Snezhnost [94]

Answer:

The solutions are the following:

  • z=2(cos(π6)+isin(π6))=√3+12i

  • z=2(cos(2π3)+isin(2π3))=−1+i√3

  • z=2(cos(7π6)+isin(7π6))=−√3−12i

  • z=2(cos(5π3)+isin(5π3))=1−i√3
