x(2x^4 - 7x^2 - 4x) BY FACORING X
If you divided an x out of 4x, how did it remain as 4x?

, not 2x4
, try instead re-writing in the manner which was provided to you earlier: 2(x2
) - 4.

+ 1)(x - 4) = 2x3
+ x - 4, then this cannot be the correct factorization.
To learn how to factor quadratics, try here
. Then try to do the factorization of 2y2
- 7y - 4, and see how that relates to the quadratic-type quartic you were provided earlier.
