$\frac{x^3 + x^2 -20x + 24}{x-3} = x^2 +4x-8$

Step-by-step explanation:

Given;

p(x) = x³ + x²- 20x + 24

factor of p(x) = x-3

Apply long division method;

x² + 4x - 8

------------------------------

x - 3 √ x³ + x²- 20x + 24

-( x³ - 3x²)

-------------------------------

4x² - 20x + 24

-(4x² -12x )

-------------------------------

-8x + 24

- (-8x + 24)

-----------------------------------------

$thus, \ \frac{x^3 + x^2 -20x + 24}{x-3} = x^2 +4x-8$
