factor the expression completely 70x - 40
To factor the expression 70x - 40 completely, we can begin by finding the greatest common factor (GCF) of the two terms.
The GCF of 70x and 40 is 10 because both terms are divisible by 10.
To factor out the GCF of 10, we divide each term by 10:
70x ÷ 10 = 7x
40 ÷ 10 = 4
Now we can rewrite the expression as:
10 (7x - 4)
Therefore, the expression 70x - 40 is completely factored as 10(7x - 4).
