QuestionHow do I factor simple addition?Community AnswerFind a common factor for the two numbers. For example, for 6 + 8, 6 and 8 share a factor of two. You can then rewrite it as 2 (3 + 4).

QuestionHow would I factor -24x+4x^2?DonaganTop AnswererBoth terms have 4x as a factor. Therefore, -24x + 4x² = 4x(-6 + x) = 4x(x - 6).

QuestionCan you demonstrate an easier problem? I have problems like 42r - 18 to factor.Community AnswerFind a common factor of 42r and 18, e.g. 6. This number will go on the outside of the bracket so 6(...). Then divide the original number(s) you had by 6. We end up with 7r-3. This will go on the inside of the bracket to make the final answer: 6(7r-3). You can check your answer by expanding the brackets again: if the answer matches what you started with, then the answer is correct!

QuestionSqrt[2(ab)^2+(ac)^2+(bc)^2)-a^4-b^4-c^4]/4. This equation is part of the proof of Heron's Formula. Could you show, step by step, how to factor it?Community AnswerUse the "guess a root" method. Saying what it's from is a huge hint. Your expression should equal 0 whenever a + b = c (degenerate triangle). That means (a+b-c) is a factor. By symmetry (a-b+c) and (-a+b+c) are also factors. Divide those out and see what's left.

QuestionHow do I factorize 4x^3 + 8x?DonaganTop Answerer4x(x² + 2).
-
QuestionHow do I factorize x^2 + 6x + 9?DonaganTop Answererx² + 6x + 9 = (x + 3) (x + 3) = (x + 3)²
-
QuestionHow do I factor -3 - p?DonaganTop AnswererThe only factor common to both terms is -1. So -3 - p = -1(3 + p). You could also write it as -(3 + p). Either way the value is the same.

QuestionHow do I factorize 5a + ax - 2b + by?DonaganTop Answerera(5 + x) - b(2 - y).
-
QuestionWhat are the factors of 2x^2 - 7x-6 = 0? I can't make it work to any of the above rules.DonaganTop AnswererYou're right, it doesn't factor.
-
QuestionHow do I do 5a - 10av?Cluster_DuckyCommunity AnswerBoth terms can be factorized as 5 and a, therefore we keep a 5a outside the bracket: 5a(1x - 2v).
-
QuestionHow do I factor 8x^2 - 14x - 15?DonaganTop Answerer8x² - 14x - 15 = (4x + 3)(2x - 5).
-
QuestionHow do I factorize 8wx + 12xyz - 24wxyz?DonaganTop Answerer8wx + 12xyz - 24wxyz = 4x (2w + 3yz - 6wyz).
-
QuestionHow do I I factor x squared -x-30+0?Community AnswerSo you have x^2 - x - 30 + 0. This factors nicely into (x-6)(x+5). To double check, multiply the factors together to make sure you get what you started with.
-
QuestionHow do I answer 3m(b - m)?DonaganTop Answerer3bm - 3m².
-
QuestionHow can I solve an algebraic expression involving a perfect square?Community AnswerIf the question is the difference of perfect squares, such as (x^2-4), you would square root both numbers and put it in this formula (x+4)(x-4).
-
QuestionHow do I factor powers in algebraic equations?Community AnswerTry to factor out common factors like 2x^2 +x; you can factor this to be x(2x+1). Do your best to simplify and cancel.
-
QuestionHow do l factorize when doing algebra?Community AnswerWhen you factorize, you are trying to find the greatest common factor. For example, take 4=2x. 2 is the is the greatest common factor because its the highest possible number BOTH numbers can be divided with.
