Question:
Factorize: 3x³ - x² - 10x
Answer:
x(x - 2)(3x + 5)
Solution:
The given polynomial is : 3x³ - x² - 10x
Now,
=> 3x³ - x² - 10x
=> x( 3x² - x - 10 )
=> x( 3x² - 6x + 5x - 10 )
=> x[ 3x(x - 2) + 5(x - 2) ]
=> x(x - 2)(3x + 5)
Moreover,
For the zeros of the polynomial , we have ;
=> x(x - 2)(3x + 5) = 0
=> x = 0 , 2 , -5/3
