Multiply the number and variable together to get 2x. Then
divide each part of the expression by 2x
. The expression with the GCF factored out is 2x (x^
2
+ 9x + 5). Note that you must put the factored expression in parentheses and write the GCF next to it.
How do you factor expressions?

What is the first step to factor an expression?
The first step in any factoring problem is
to factor out the GCF
. Arrange the 4 terms into 2 groups of 2 terms each so that each group of 2 terms has a GCF. Factor the GCF from each group of 2 terms. If the two, new terms formed by step 2 have a GCF, then factor it out.
How do you factor Binomials step by step?
Step 1:
Group the first two terms together and then the last two terms together
. Step 2: Factor out a GCF from each separate binomial. Step 3: Factor out the common binomial. Note that if we multiply our answer out, we do get the original polynomial.
What are the 7 factoring techniques?
- Factoring out the GCF.
- The sum-product pattern.
- The grouping method.
- The perfect square trinomial pattern.
- The difference of squares pattern.
How do you factor with two variables?
- Multiply the leading coefficient by the last number.
- Find the sum of two numbers that add to the middle number.
- Split the middle term and group in twos by removing the GCF from each group.
- Now, write in factored form.
How do you factor with only 2 terms?
First, identify the factors in the expression. Next, use the zero-product property to split these factors into separate equations. Finally, solve each equation to get the solutions to your original equation!
What are the factors of 18?
Factors of a number are the numbers that divide the given number exactly without any remainder. According to the definition of factors, the factors of 18 are
1, 2, 3, 6, 9, and 18.
What are the 4 methods of factoring?
The four main types of factoring are
the Greatest common factor (GCF), the Grouping method, the difference in two squares, and the sum or difference in cubes
.
How do you factor if there is no GCF?
- Step 1: Group the first two terms together and then the last two terms together.
- Step 2: Factor out a GCF from each separate binomial.
- Step 3: Factor out the common binomial.
How do you factor three variables?
- Multiply the leading coefficient by the last number.
- Find the sum of two numbers that add to the middle number.
- Split the middle term and group in twos by removing the GCF from each group.
- Now, write in factored form.
How do you factor variables?
You can factor out variables from the terms in an expression. You factor out variables
the same way as you do numbers
except that when you factor out powers of a variable, the smallest power that appears in any one term is the most that can be factored out.
How do you solve a binomial with two variables?
- Multiply the first term of each binomial together.
- Multiply the outer terms together. (2x)(–1) = –2x.
- Multiply the inner terms together. (3)(3x) = 9x.
- Multiply the last term of each expression together. …
- List the four results of FOIL in order.
- Combine the like terms.
Is 18 a perfect square?
Integer Perfect square | 18 x 18 324 | 19 x 19 361 | 20 x 20 400 | 21 x 21 441 |

What two numbers are both factors of 18?
Testing the integer values 1 through 4 for division into 18 with a 0 remainder we get these factor pairs: (1 and 18), (2 and 9), (3 and 6). The factors of 18 are
1, 2, 3, 6, 9, 18
