You would factor out -1 (a) from a trinomial in an equation such as -a^2 +30a - 2a + 60 after the middle term has been separated. The final answer of this trinomial would then be (a-30) (a-30).
(x + 1)(x - 4)
(3x+1)(x+2)
Suppose the trinomial is x2 + Bx + C You need to find a factor pair of C whose sum is B. If the factors are p and q (that is, pq = C and p+q = B), then the trinomial can be factorised as (x + p)*(x + q).

Do in this order. 1. All, find the gfc 2. Binomial, factor as difference of squares, sum of cubes, difference of cubes. 3. Trinomial, factor as a quadratic. 4. 4 or more terms, factor by grouping.
You would most likely factor out -1 from a trinomial when it has a leading coefficient that is negative. This can simplify the expression and make it easier to factor further, especially if you want to rewrite it in a standard form or if you are looking for real roots. Additionally, factoring out -1 can help in situations where the trinomial needs to be set to zero for solving equations, making the subsequent steps clearer.
If the coefficient of the highest power of a variable of interest is negative.
A factor of a perfect square trinomial is eithera number that is a factor of each term of the trinomial,a binomial that is a factor of the trinomial, ora product of the above two.For example, consider 4x2 + 8x + 4It has the factors2 or 4,(x + 1) or2x+2 = 2*(x+1) or 4x+4 = 4*(x+1)
1, 5 and 6 x^2 + 5x + 6 = (x + 2)(x + 3)
You would most likely factor out -1 from a trinomial when the leading coefficient is negative or when doing so simplifies the expression. For example, if a trinomial is written as (-x^2 + 3x - 2), factoring out -1 would make it easier to identify common factors or rearrange the expression into a more standard form, like (x^2 - 3x + 2). This can also help in solving or graphing the polynomial more effectively.

(x + 1)(x - 4)
To factor the trinomial (7x^2 + 7x - 14), first factor out the common factor of 7: [ 7(x^2 + x - 2) ] Next, we can factor the quadratic (x^2 + x - 2) into ((x + 2)(x - 1)). Thus, the complete factorization of the original trinomial is: [ 7(x + 2)(x - 1) ]
(x - 4)(x - 1).
(5x - 1)(x + 3)
(x - 1)(x - 14)
just make the trinomial easier to factor. ex -x2 + 3x + 4 ... most books don't teach you how to factor when a leading term is negative. ... so -1(x2- 3x- 4) ... now factor again ignoring the -1 -1(x - 4)(x + 1)
