A binomial is an expression with two terms combined by either addition or subtraction sign To factor a binomial the following four rules are applied ab ac a b c a 2 b 2 a b a b a 3 b 3 a b a 2 ab b 2 a 3 b 3 a b a 2 ab b 2 Example 6 Factor xyz x 2 z Solution Factoring by Grouping We often see the grouping method applied to polynomials with 4 terms The idea is to pair like terms together so that we can apply the distributive property in order to factorize them nicely Factor x 3 3x 2 x 3 x3 3x2 x 3 We have begin aligned x 3 3x 2 x 3 x 2 x 3 x 3 x 2 1
FACTOR BY GROUPING Group terms with common factors Factor out the common factor in each group Factor the common factor from the expression Check by multiplying the factors Factoring by grouping involves grouping terms then factoring out common factors Here are examples of how to factor by grouping Example with trinomial 3x2 16x 12 where ax2 3x2 bx 16x c 12 To use grouping method you need to multiply ax2 and c which is 36x2 in this example

In this explainer we will learn how to factor expressions by grouping Let us begin by revisiting the idea of factoring an expression by identifying its highest common factor Suppose we have 3 9 6 Since each term is divisible by 3 we can say that it is a common factor of the expression Answer Rewrite the middle term 11z 11z as 3z 8z 3z 8z from the chart above 6z 2 3z 8z 4 6z2 3z 8z 4 Group pairs Use grouping to consider the terms in pairs left 6z 2 3z right left 8z 4 right 6z2 3z 8z 4 Factor 3 3z out of the first group and 4 4 out of the second group
For these trinomials we can factor by grouping by dividing the x term into the sum of two terms factoring each portion of the expression separately and then factoring out the GCF of the entire expression The trinomial 2x2 5x 3 2 x 2 5 x 3 can be rewritten as 2x 3 x 1 2 x 3 x 1 using this process Solution Step 1 Find the product ac 5 6 30 Step 2 Find of two factors of 30 that add up to 13 3 and 10 Step 3 Write 13x as the sum of 3x and 10x 5x 2 3x 10x 6 Step 4 Group the two pairs of terms 5x 2 3x 10x 6 Step 5 Take out the common factors from each group x 5x 3 2 5x 3
