How do you factor 100V square minus 25W square?
100 V2 - 25 W2 = (10V + 5W) (10V - 5W)Another way to show it:100 V2 - 25 W2 = 25 (4 V2 - W2) = 25 (2V - W) (2V + W)
What is w to the second power divided by 3w to the second power?
w2/(3w)2 = w2/9w2 = w2-2/9 = w0/9 = 1/9 or w2/3w2 = 1/3
How do you factor w2 18w 81?
(w + 9)(w + 9)
The length of a rectangle is 6 meters more than its width If the area is 135 square meters what is its width?
