Factorization of trinomials
The general form of the trinomial is (x 2 + cx + d) where c and d have different numerical values: c = a + b, and d = ab. In the given trinomial expression if all terms are positive, then both the factors are positive. If the middle term is negative,..
Factorising a trinomial by splitting the middle term
The general form of the trinomial is (x 2 + cx + d) where c and d have different numerical values: c = a + b, and d = ab. In these examples, study the relation between the middle and the last terms. Therefore, to factorise expressions of the type (x 2 + cx + d), we have to find two ..

Access full lesson containing this video at: www.yourteacher.com Students learn that a trinomial in the form x^2 + bx + c (where c is negative), such as x^2 + 6x -- 27, can be factored as the product of two binomials, in this case (x + 9)(x -- 3). The first term in each binomial comes from the factors of x^2, x and x. The second term in each binomial comes from the factors of the constant term, --27, that add to the coefficient of the middle term, +6, which in this case are +9 and --3....

Question : Is the trial and error method the best to you guys in factoring trinomials? Is there another method that doesn't involve guessing? I have problems with this trial and eroor method; any tips to make this a little more easier for me, thank you guys.
Answer : Trial and error method is good when you factor trinomials that has integer factors. When you have fractions or radicals it is a real headache to get them by trial and error method. I suggest you to use general formula: Expression of the type: ax^2 + bx + c = 0 with a, b, c constants: x1 = [ -b + sqrt(b^2 - 4*a*c)] / 2a x2 = [-b - sqrt( b^2 -4*a*c)] / 2a. Good luck..

Question : I'm in algebra and my teacher, Mrs.Nelson, is the most God awful teacher on the face of the planet. She thinks she's teaching, but she's really just making things harder to understand. This week she's been making factoring trinomials hard to understand, and now I've got all this homework that I just can't get. Could anyone explain to me (in an understandable way) how to factor trinomials in ax squared+bx+c form?
