Find the GCF of 20x − 4 .(1 point)
The greatest common factor (GCF) of a polynomial is the largest polynomial that divides each term evenly. To find the GCF of 20x and -4, we need to consider the constants and any variables.
Looking at the numbers 20 and -4, the largest integer that divides both numbers without leaving a remainder is 4. Since the term with x (20x) has the variable and the constant term does not, the variable is not included in the GCF.
Therefore, the GCF of 20x and -4 is 4.
