URGENT!Write the polynomial 3x(x-4)(x+1) in standard form.Then classify it by degree.Do I just factor?Help

[From: ] [author: ] [Date: 11-06-05] [Hit: ]
combining like powers, then multiply by 3x.......
3x(x-4)(x+1)
(3x^2-12x)(x+1)
3x^3+3x^2-12x^2-12x

3x^3-9x^2-12x
This is a cubic polynomial which goes up as x gets bigger

URGENT!Write the polynomial 3x(x-4)(x+1) in standard form.Then classify it by degree.Do I just factor?Help?

it is factored ! You have to expand...

3x(x - 4)(x + 1) = 3x(x^2 - 3x - 4) = 3x^3 - 9x^2 - 12x

this is a third degree polynomial (trinomial).

You need to practice...read your textbook...practice some more !

It's already factored. You want to multiply the factors and combine terms with the same power. Use the FOIL method to multiply the two binomials, combining like powers, then multiply by 3x.
