Answer:

The answer to your question is 2(x - 9/2)(x - 3/5)

Step-by-step explanation:

Polynomial           20x² - 102x + 54

Process

1.- Find the Greatest Common Factor

                            20   102   54   2

                             10     51    27  2

                              5      51    27  3

                              5      17      9  3

                              5       17     3  3

                              5       17      1  5

                               1       17         17

                                         1

GCF = 2

2.- Factor 2

                        2(10x² - 51x + 27)

3.- Factor   10x² - 51x + 27

Use the general formula to solve this equation

                        x = \frac{-b +- \sqrt{b^{2} - 4ac}}{2a}

a = 10   b = -51   c = 27

                        x = \frac{51 +- \sqrt{51^{2} -4(10)(27)}}{2(10)}

-Simplification

                       x = \frac{51 +- 39}{20}

-Result

                        x₁ = 9/2       x₂ = 3/5

                       (x - 9/2)        (x - 3/5)

4.- Answer

                      2(x - 9/2)(x - 3/5)
