Find the GCF of 20x − 4 .(1 point)
The GCF (Greatest Common Factor) of 20x - 4 is 4.
To find the greatest common factor (GCF) of 20x − 4, we need to factorize the expression.
First, let's start by factoring out the common factors of 20 and 4.
20x − 4 = 4(5x − 1)
Next, we can simplify the expression further by factoring out the greatest common factor of 4 and 5x − 1.
The GCF of 20x − 4 is 4.
To find the greatest common factor (GCF) of a polynomial, you need to factor it into its prime factors and then find the common factors. Let's factor the polynomial 20x - 4.
First, we look for the greatest common factor of the coefficients (the numbers in front of the variables). In this case, both 20 and 4 are divisible by 4. So, we can factor out 4 from both terms to get:
4(5x - 1)
Now, let's look at the variables. In this case, there is only one variable, which is 'x'. Since there is no other common factor between the coefficients and the variable, the GCF is just 4.
So, the GCF of 20x - 4 is 4.
