Which two values of x are roots of the polynomial below x^2-11x+17

Answer

9.14   and 1.86

Explanation

x²-11x+17

The first thing is to equate it to zero.

x²-11x+17 = 0

x²-11x = -17

x² - 11x + (11/2)² = -17 + (11/2)²

(x² - 11/2)² = -17 + 121/4

(x - 11/2)² = 13.25

x -11/2 = √13.25                            or      x - 11/2 = -√13.25

x = √13.25 + 11/2                                            x = -√13.25 + 11/2

   = 3.64 + 5.5                                                     = -3.64 + 5.5

   = 9.14                                                              = 1.86

9 x 8 divided by (5-3)=36

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
