I am to factor this completely and I am stuck. 2r^3 + 8r^2 +6r Note: x^2 is x-squared (that is, x with the superscript 2), etc. 2 is a factor and r is a factor so the equation becomes 2r(r^2 + 4r + 3) then we can factor the term in parentheses. To do that, we know the first ...

I am to factor this completely and I am stuck. 2r^3 + 8r^2 +6r Note: x^2 is x-squared (that is, x with the superscript 2), etc. This is a double post. The equation is r but the explanation for the squared term uses x's.

Old Factor qstn:BobP
Bob, I did eventually find a factorization for the expression x^4 + 2x^3 + 4x^2 + 8x +16 The original problem was probably something like x^5-32=0. I think the poster divided (x-2) into it to get the expression above. This of course is the 5th roots of 32, x=2 being the only ...

Chemistry - Van't Hoff Factor
How does the van't hoff factor relate to freezing points? If one van't hoff factor is bigger than another, is its freezing point lower or greater? delta Tf = iKfm. So increasing i will increase delta Tf Van't Hoff factor is the concentration of particles in a solute, so, if it...

Factor 3x^2 - 4x + 1 these aswell x^2 - 16 x^2– 6x + 9 a^2- 2ab + b^ 2 x^2+ 6x -16 x^2– 6x -16 (3x +a )(x +a ) 3a +a= -4, so what is a?

How do I factor these: 2x2 - 16x + 30 4x^2-9 x^2-5x 5x^2-26x+5 25x^2+4 Example: 2x^2 - 16x + 30 = 2 (x^2 - 8 x + 15) 2(x - 5)(x - 3) The first, factor out a 2 first. Then factor . The second...difference of two squares Third factor out an x I will be happy to critique your ...

can someone please explain to me how to factor by grouping!

factor the trinomial by grouping
Usually factoring by grouping is useful when patterns jump out at you: x^3 + 3x^2 - 6x - 18 you can see x(x^2-6) + 3(x^2-6) In your problem, that's not likely, so grouping is not a useful method. Instead, factor out the 3x to get 3x(5x^2 - 3x - 2) Now, if you want to use ...

I can not factor that except by 1
I can factor 4x^2-17 but not 4x^2-17 The only factor I know of is 1.

no, if you foil out your factor it will come out as 6x^12 + 20x^6 + 6. i am not familiar with the U substitution but if you try again i can tell you if you are right.

no it is c^2 -8c + 16 - y^2 and it says to factor completely

6x^6 + 13x^3 - 5 let u = x^3 6u^2 + 13u -5 = (3u -1)(2u +5) Which is the same as (3x^3 -1)(2x^3 + 5) That leaves you with two cubics to factor. One of the factors of (3x^3 -1) is (3^1/3)*x -1 (I am using "3^1/3)" to denote "cube root of"). The other factor is ( [3^2/3)x^2 + (3...

Umm, If I can remember correctly, there is only 3 terms, so you don't have to factor by grouping. I'm not sure if this is right or not but I'll try it. I got 2t^2-23t-45 then I use FOIL (2t - 5 )(t - 9 ) < answer

Did not have to factor by grouping, but it was easier that way because the grouping was given. I did it the conventional way to check.

factor the trinomial by grouping
15x^3-9x^2-6x Can someone please show me how to factor completely.. trying to learn how to do factoring

please help math factor trinomial
first notice that you can factor out the y, leaving y(y^2-13y+36) Now you want two numbers that add to -13 and multiply to 36. Obviously they must both be negative. Easy factors of 36 are 1,36 2,18 3,12 4,9 It's clear that we want 4 and 9, so our polynomial is y(y-4)(y-9) This...

factor label method (chem)
Two ways. #1. Use the formula. mass = volume x density. mass = 3.55 mL x 13.6 g/mL = ?? #2. Since you have this labeled factor label method, perhaps you want to use that method. mass = (13.6 g/mL)x 3.55 mL ?? See mL cancels and leaves g which is what you want in the answer.

Using the factor Theorem
use the factor theorem to determine whether x-c is a factor of f(x) f(x)=x^3+8x^2-18x+20; x-10 I have a doubt in my answer, i determined that x-10 is not a factor... am i right? please verify as my exam is tomorrow night at college. thank you for your time and hard work:)
