Answer:

(x+1)(x²-4x+1)

Step-by-step explanation:

f(x) = x³-3x²-3x+1

= (x³+1) - 3x (x+1)

= (x+1)(x²-x+1) - 3x(x+1)

= (x+1)(x²-x+1-3x)

= <u>(x+1)(x²-4x+1)</u>

<u />

** (x+1)(x²-4x+1) = (x+1)((x-2)² - 3)

= (x+1)((x-2)² - (√3)²)

= (x+1)(x-2-√3)(x-2+√3)

$-\frac{4}{6} + -\frac{7}{9}$ = $-\frac{13}{9}$

Step 1: Cancel 4/6 and change to 2/3.

$= -\frac{2}{3} - \frac{7}{9}$

Step 2: Adjust Fractions based on the LCM.

The LCM of 3 , 9 : 9

$= -\frac{6}{9} - \frac{7}{9}$

$= \frac{-6 - 7}{9}$

Step 3: Subtract the numbers : - 6 -7 = -13

$= -\frac{13}{9}$
