How is subtracting like fractions similar to adding like fractions

Answers

Because they both have the same rule. They have to have the same denominator.
Well,

Adding and subtracting like fractions are similar in that both cases simply require you to add the numerators.  This is opposed to adding and subtracting non-like fractions because you have to convert them into like fractions.

A state lottery commission analyzes the ticket purchasing patterns of its citizens. The following expression is developed to help officials calculate the likely number of people who will buy tickets for a certain size jackpot. 81a^2-36b^2
Factor the expression completely.

Answers

So,

We first factor out the GCF.

9(9a^2-4b^2)

Now, we notice that the expression is a difference of two perfect squares.
9(3a+2b)(3a-2b)

The expression is now factored completely.

9(9a^2-4)

9(3a+2)(3a-2)

I hope this helps!
