How do you rewrite expressions using the distributive property? Not simplifying.

Question

7r+8r+2, 3a+6b, x(6+8), 2(5x+8y) I don't understand how to rewrite them.

Answer 1

You need to use the distributive property a(b + c) = ab + ac

and vice versa ab + ac = a(b + c)

Let's do the first expression

7r + 8r + 2 

As you can see in first two terms r is common so take out common

r(7 + 8) + 2

The other way of doing it is you can take the GCF of both terms.

For second expression 3a + 6b 

GCF of 3a and 6b is 3

so, take that out and rewrite the expression as 3(a + 2b)

Try doing other expressions and if you're still not able to work myself or any other tutor will be glad to help you.
