You may notice that all of the terms have a common factor: . So, let's take the
out of all the terms. This gives us:
Using the Zero Product Property, we can say that both and
.
Let's solve both. is obvious, but we still need to solve our other term:
Our answer is x = -6, 0, 4.
Answer:
So the factors and multiples of 42 are 1, 2, 3, 6, 7, 14, 21, 42
Step-by-step explanation:
Factors are what you can multiply to get a number and a multiples are what you get after multiplication. We can determine the factors of 42. The multiples of 42 are:
So the factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42
The multiples of 42 are 1,2,3,4,5,6 etc
So common multiples and factors are 1, 2, 3, 6, 7, 14, 21, 42
