Question

x4 + 3x3 + 3x2 + x + 1​

Answer 1

Answer:

5x+16 hope it's help you then follow me

Answer 2

Answer:

x4 - 3x3 + 3x2 - x + 1

Step-by-step explanation:

((((x4)-(3•(x3)))+3x2)-x)+1

STEP 2 :

Equation at the end of step2:

((((x4) - 3x3) + 3x2) - x) + 1

STEP3:

Polynomial Roots Calculator :

 3.1    Find roots (zeroes) of :       F(x) = x4-3x3+3x2-x+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      9.00        1     1      1.00      1.00   

Polynomial Roots Calculator found no rational roots

Final result :

x4 - 3x3 + 3x2 - x + 1
