The general form of quadratic trinomial formula in one variable is ax 2 + bx + c, where a, b, c are constant terms and neither a, b, or c is zero. A trinomial can be factorized in many ways. If ax 2 is negative in a trinomial, you can factor −1 out of the whole trinomial first.įactoring a trinomial means expanding an equation into the product of two or more binomials.First factor the common factor then factor the rest of the expression. Look for common factors for the trinomial ax 2 + bx + c, where a is 1.If the last term and the first term of the trinomial are positive but the middle term is negative, then both signs of the binomials will be negative.(The greater factor will be negative and the smaller will be positive). If the middle term and the last term of the trinomial are negative and the first term is positive, then the sign for one binomial will be positive and the other will be negative.

(The greater factor will be positive and the smaller will be negative).

If the last term of the trinomial is negative but the middle term and the first term are positive, then one term of the binomial will be negative and the other will be positive.

If all terms of the trinomial are positive, then all terms of the binomials will be positive.

These rules are based on mathematical signs such as (+) and (-) that play an important role while factoring trinomials and make it simple in factoring trinomials. For factoring a trinomial there are points or rules to remember.
