Question

Factor completely over the set of integers:

-2x^4 + x^3 + 18x^2 - 9x

Answer 1

Answer:-x( x-3 ) ( x + 3 )(2x-1)

Explanation:

Find the first factor which is : -1 ( 2 x 3 -x2- 18 x + 9)

Find the second factor which is : -x( x - 3)( 2 x 2+ 5x - 3)

Find the third which is: -x( x - 3) (x + 3) (2x - 1)

Find the fourth which is : -x ( x - 3) (x + 3 ) (2x - 1)
