Question

11) factorize the Polynomial X3-3x2-10k+24 if (x-2) is a factor​

Answer 1

x³ 3x²10x + 24

To show if (x - 2) is a factor, it is enough to show that at x = 2, value of the polynomial is zero.

.. (2)³ - 3(2)² – 10 (2) + 24

⇒8-12-20+ 24 = 0

Hence, (x - 2) is a factor of polynomial.

Answer 2

Step-by-step explanation:

x

3

−3x

2

−10x+24

To show if (x−2) is a factor, it is enough to show that at x=2, value of the polynomial is zero.

∴(2)

3

−3(2)

2

−10(2)+24

⇒8−12−20+24=0

Hence, (x−2) is a factor of polynomial
