Let’s break it down! You can factor out the 9 here:
. Now, add the numbers inside the parentheses:
.
So, it simplifies to:
.

That’s how you turn a complex-looking equation into a simple calculation. Fun, right?

Also, did you know that factoring in math can save you time and make calculations way easier? Instead of multiplying each part separately and adding them, this method cuts the work in half! Try it out in other similar equations, and you’ll impress your friends with your math wizardry!
