Understanding the difference between expressions, equations, and identities is key to avoiding confusion and making careless mistakes. Must be steady, pom pee pee!
Let's dissect these identities like a frog in Biology class (but hopefully less squeamish!).
This identity tells us that when you square the sum of two terms (a and b), you get the square of the first term (a²), plus twice the product of the two terms (2ab), plus the square of the second term (b²).
Example: Expand (x + 3)²
Using the identity: (x + 3)² = x² + 2(x)(3) + 3² = x² + 6x + 9
This identity is similar, but with a crucial difference: when you square the *difference* of two terms (a and b), you get the square of the first term (a²), *minus* twice the product of the two terms (-2ab), plus the square of the second term (b²).
Example: Expand (2y - 1)²
Using the identity: (2y - 1)² = (2y)² - 2(2y)(1) + 1² = 4y² - 4y + 1
Fun Fact: Did you know that these identities are derived from the distributive property of multiplication? It's all about expanding (a + b)(a + b) or (a - b)(a - b). Try it out yourself!
