Simplify

4x^3 - 2x^2 - 36x +18 = 0

4x^3 - 2x^2 - 36x +18 = 0

#2

just remember do not divide by cero, or somthing bad will happen. Dont believe that other wanker how started that thread.

Things like that are too serious to be joked about.

Put that sh

That probably didn't make much sense to you...

**it in your calculator to get a zero that is also a possible factor and then do long division or synthetic division to get a factor. Then factor the left over trinomial.**That probably didn't make much sense to you...

#4

divide everything by two. after that, it really doesnt get much more simplified than a basic polynomial. you sure you dont mean to SOLVE that or to FACTOR that?

no. not at all.

no seriously i did understand, and yes. use a calculator. thats what they are there for.

yeah i divided everything by 2, but yes, i need to factor from there....sorry

it's:

2(2x^3 - x^2 - 18x + 9)

#7

I just finished factoring, way to give me that thign I suck most at.

f*ck factoring, look in the back of your textbook.

#8

because it factors to (2x-1)(x-3)(x+3)

so your solutions are x= 1/2, 3, -3

so your solutions are x= 1/2, 3, -3

#9

because it factors to (2x-1)(x-3)(x+3)

so your solutions are x= 1/2, 3, -3

THANK YOU

i owe you big time...

ha no problem.

Im a math major, so once i saw it, I couldnt let myself not do it

#11

divide by 2 then group

4x^3 - 2x^2 - 36x +18 = 0

2(2x^3-x^2) + (-18x +9)

2(x^2(2x - 1) - 9(2x - 1)

2(x^2 - 9)(2x - 1)

^squares

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

4x^3 - 2x^2 - 36x +18 = 0

2(2x^3-x^2) + (-18x +9)

2(x^2(2x - 1) - 9(2x - 1)

2(x^2 - 9)(2x - 1)

^squares

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

#12

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

It's probably useless that I gave you only the answer.

I'll try and type it up.

EDIT: I did it different then the guy above... not gonna bother cause I'm not sure how I could explain it through a post.
