Answer:
Step-by-step explanation:
Using the law if indices
×
=
Thus to simplify the expression add the 3 exponents
a(b + c) + b(c - a) + c(a - b) ← distribute parenthesis
= ab + ac + bc - ab + ac - bc ← collect like terms
= 2ac
Then the expression simplifies to
<h2>Question: Factor: 4x2 + 4x</h2>
Find the GCF.
Factor out the GCF.
Simplify each term in parentheses.
Hence, the answer is 4x(x + 1).
