In this video the instructor shows how to factor a trinomial with negative leading coefficient. Most of the students are confused when they have to factor a trinomial with a negative leading coefficient. But there are many ways to solve these kind of problems as shown in this video. One way you can do is that take out the greatest common factor GCF of -1 from the equation. So pulling the -1 gives you the original trinomial with all the signs of the terms changed. Now go on and factor the new trinomial by the normal procedure.

If so, factor out the GCF. Do not forget to include the GCF as part of your final answer. Step 3: Multiply the leading coefficient and the constant, that is multiply the.

In mathematics , a coefficient is a multiplicative factor in some term of a polynomial , a series , or any expression ; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters , and must be clearly distinguished from the other variables. The third term 1. The final term does not have any explicitly written coefficient, but is considered to have coefficient 1, since multiplying by that factor would not change the term. Often coefficients are numbers as in this example, although they could be parameters of the problem or any expression in these parameters. In such a case one must clearly distinguish between symbols representing variables and symbols representing parameters.

A "hard" quadratic is one whose leading coefficient that is, whose numerical value on the x 2 term is something other than a nice, well-behaved 1. To factor a "hard" quadratic, we have to handle all three coefficients, not just the two we handled in the "easy" case, because the leading coefficient adds to the mix, and makes things much messier. The first step in factoring these hard quadratics will be to multiply " a " and " c ". Then we'll need to find factors of the product " ac " that add up to " b ". So the "adding up to" part is the same we're still finding factors that add up to the middle term's coefficient , but finding those factors will be harder, because we've got more information going into that stage of the process. Trinomials with Lead Coefficients. However, hard factoring is still quite do-able.

Factor Trinomial with Negative Leading Coefficient

Example 1 Factor:. Example 2 Factor:. Example 3 Factor:. Example 4 Factor:. Make sure that the trinomial is written in the correct order; the trinomial must be written in descending order from highest power to lowest power.

So, you are factoring trinomials and when you get to a trinomial that has a lead coefficient greater than 1, you start to panic. Does that sound familiar? Yes, you've probably discovered that these trinomials are a little more difficult to factor. But, no worries, if you can factor by grouping , then I am going to show you a very simple, easy way to factor these trinomials. Factor the trinomial: 3x 2 - 24x - 8.
