Step 2 : Find two numbers such that the product is equal to a·c and the sum is equal to the middle coefficient, b. Step 1 : Multiply the leading coefficient and the constant term (number without variable). While not every equation can be solved using factoring, using this method whenever possible can save some time and also strengthen your factoring abilities. First we can check for any common factors. Steps to Factor a Trinomial using the Box Method. You need to identify two numbers whose product and sum are c and b, respectively. So split up 19x into 15x + 4x (or 4x + 15x), then factor by grouping: 6x2 + 19x + 10 6x2 + 15x + 4x + 10. The Albert Team Last Updated On: MaSolving quadratic equations by factoring is one of the most efficient methods for finding the roots (solutions) of a quadratic equation. To factorize a quadratic equation of the form x 2 + bx + c, the leading coefficient is 1.

In this example, the first terms are 2t and 9.

These numbers (after some trial and error) are 15 and 4. Here is an example: (2t + 1) (9 - s) The first step is to multiply the first terms from each binomial. The box is just a 2x2 square that we use to put the. We can use the zero-product property to solve quadratic equations in which we first have to factor out the greatest common factor (GCF), and for equations that have special factoring formulas as well, such as the difference of squares, both of which we will see later in this section. 610 60, so we need to find two numbers that add to 19 and multiply to give 60. Factoring using the box method is probably the best way to factor a trinomial of the form ax2 + bx + c. For example, equations such as 2+x - 6=0 is in standard form. An equation containing a second-degree polynomial is called a quadratic equation.
