Question

Using the Factor Theorem, show that (x-3) is a factor of the polynomial x³+3x²-10x -24. Hence, factorise the polynomial completely​

Answer 1

Answer:

yes, (x-3) is the factor of polynomial x³+3x²-10x-24

Step-by-step explanation:

given: x-3 = x-3=0

x = 0+3 => x= 3

putting the value of x in the given polynomial we get :

(3)³+ 3(3)² - 10(3) - 24

27 + 27 - 30 - 24

54 - 54 = 0

therefore, polynomial factories completely
