SIMPLIFYING EXRESSIONS
Sometimes “real world” applications do not always apply.
This week’s assignment
characterizes three different equations.
All of which use the
distributive property
to solve the
equation.
Using the
distributive property
removes the parenthesis from the equation. By
combining
like terms,
after removing the parenthesis, we can retrieve the
simplified
answer. By
using following each step and showing my work, you then would understand how to simplify
expressions by using the
distributive property
.
2a(a-5)+4(a-5)
Distributive property
removes the parenthesis
2a
2
-10a+4a-20
Combine
like terms
2a
2
-6a-20
Simplified
due to no more
like terms
In this equation the
coefficient
is
the 2 at the beginning of the equation. First you start
with the
coefficient
and multiply 2a by both the (a-5), than you multiply the 4 by the same (a-5).
By doing this first of
distributive property
sets you up for the next part, combining
like terms.
