Find the rational solution of x3 – 3x2 + x + 5 = 0. show your use of the rational zero theorem to receive credit!

       A zero of a function is a number that, when plugged in for the variable, makes the function equal to zero.
P ( x ) = 0
As P ( - 1 ) = 0:
( x³ - 3 x² + x + 5 ) : ( x + 1 ) = x² - 4 x + 5
 -x³ -  x²

      - 4 x² + x
        4 x²+ 4 x
       
                 5 x + 5
                -5 x -  5
               
                          0
The remaining trinomial: x² - 4 x + 5 doesn´t have rational roots.
x = -1

The point (5, 10) will work for the rule y=x+5.y= 10 x= 510=5+510=10therefore the ordered pair (5, 10) works for the rule
