Factor the expression 54x+81 using gfc

Answers

Answer 1
Answer:

We can factor a binomial by taking out the gcf (common factor) . We can factor the binomial as following:

54x = 27 * 2x

81 = 27 * 3

Here, 27 is the common factor of both the terms. So, by taking out 27 as a common factor we will get,

54 x + 81

= 27 (2x + 3)

So, the factor form of the given expression is 27 (2x + 3)

Hope this helps you!
