NASA’s Curiosity Rover Lands on Mars!
On Monday, August 6, 2012, NASA’s Curiosity Rover landed on Mars, traveling a total of 8.5 months and 352 million miles. This project cost a whopping $2.5 billion to create!
One of the amazing abilities that this amazing vehicle can do is take pictures and send them back to earth for us to look at. Check out some of the pictures here: http://www.nasa.gov/mission_pages/msl/multimedia/gallery-indexEvents.html
We can use the division of polynomials to find the length, and our knowledge that area is equal to the length multiplied by the width. Since we’re finding the length, we take the expression for area and divide it by the expression for the width.
After reviewing the concept, we can use long division to divide these polynomials.
Now we want to subtract, and then bring down. Notice how I put parentheses around the whole expression, since we’re subtracting the whole expression.
