Question

X^3-3x+2 / let us factorise the following polynomial:

Answer 1

Step-by-step explanation:

x³ - 3x + 2

x=1 पर (1)³ - 3(1) + 2

1 - 3 + 2 = 0

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

x - 1 ✓ x³ - 3x + 2 \_x² + x - 2

-x³ + x²

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

x² - 3x + 2

-x² + x

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

-2x + 2

+2x - 2

-----------

00

-----------

(x - 1) ( x² + x - 2)

(x - 1) ( x² + 2x - x - 2)

(x - 1) {x(x+2) -1(x+2)}

(x - 1) (x - 1) (x + 2)

(x - 1)² (x + 2)
