Algebra Must-Know Manipulation Trick: Part 1

The square of sums identity and cube of sums identity is something many of us learn in school. But why is it so useful? Let me show you with today’s problem which will demonstrate one of the most important manipulation techniques you will ever learn in algebra: Finding a sum of variables without actually finding the value of each individual variable. You will see this used SO many times in many areas of math. So given that a + b = 1, a^2 + b^2 = 2, find me a^4 + b^4. No, the answer is not 4. This is part 1 of a 3-part series coming this month!
