+%285x-2%29%285x%2B2%29+
Using FOIL .... find the products and then add
F: +5x+%2A+5x+=+25x%5E2+
O: +5x+%2A+2+=+10x+
I: +5x+%2A+-2+=+10x+
L: +-2+%2A+2+=+-4+
Add
+25x%5E2+%2B10x-10x-4+
Combine like terms
+25x%5E2+-+4+
ANY two binomials, when they are the EXACT sam numbers and one of the signs is positive and the other is negative, is considered a special product. This one being the difference of two squares, and it will always come back into this form:
+x%5E2+-+y%5E2+=+%28x-y%29%28x%2By%29+
Memorize this pattern
