Rewriting the whole as an Equivalent Fraction

4.1   Adding a fraction to a whole

Rewrite the whole as a fraction using  x2  as the denominator :

                      4x4 - 3x3 - 2x     (4x4 - 3x3 - 2x) • x2

    4x4 - 3x3 - 2x =  ——————————————  =  —————————————————————

                            1                     x2          

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Pulling out like terms

5.1     Pull out like factors :

  4x4 - 3x3 - 2x  =   x • (4x3 - 3x2 - 2)  

Polynomial Roots Calculator :

5.2    Find roots (zeroes) of :       F(x) = 4x3 - 3x2 - 2

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  4  and the Trailing Constant is  -2.

The factor(s) are:

of the Leading Coefficient :  1,2 ,4

of the Trailing Constant :  1 ,2

Let us test ....

  P    Q    P/Q    F(P/Q)     Divisor

     -1       1        -1.00        -9.00      

     -1       2        -0.50        -3.25      

     -1       4        -0.25        -2.25      

     -2       1        -2.00        -46.00      

     1       1        1.00        -1.00      

     1       2        0.50        -2.25
