Now if you're required, multiply the remaining terms
Final Answer (if you are required to multiply them back together):
So basically the original expression
simplifies to this expression
Check:
Here's a way to check if you simplified it right. Simply graph the original expression
Original expression:
Graph of :
and graph the simplified expression
Simplified Expression:
Graph of :
and you'll notice that the two equations plot the same curve (if they were on the same graph, they would overlap each other). Since this shows that the two equations are equivalent, this verifies our answer.
