Topic	How do you interpret this algebraic partitioning problem?
jramirez23 08/04/18 8:24:15 PM #1:	Make me two parts of 10 such that each part multiplied by itself, and the one multiplication taken from the other leaves 49. I ask what are the parts. I ended up writing x + y = 10 x^2 + xy + y^2 = 49. That's not the right interpretation though. Apparently the correct approach is this: x + y = 10 x^2 - y^2 = 49 Hint: "taken from the other" means subtraction somehow. Does it make sense, or do you find these word problems to be tricky too? --- I consider it completely unimportant who in the party will vote, or how; but what is extraordinarily important is this who will count the votes, and how. <cite>jramirez23 posted [p:906277252] in How do you...
