Welke gelijkeid is juist ?
|
|---|
| A. a² + b² = (a + b)(a − b) |
| B. a² + b² = a² + 2ab + b² |
| C. a² + b² = (a + b).(a + b) |
| D. (a + b)² = a² + b² |
| E. (a + b)² = (a + b)(a + b) |

| A. a² + b² = (a + b)(a − b) |
| B. a² + b² = a² + 2ab + b² |
| C. a² + b² = (a + b).(a + b) |
| D. (a + b)² = a² + b² |
| E. (a + b)² = (a + b)(a + b) |
Oplossing - Solution
Toch niet te snel geantwoord ?
Zoals 5² = 5.5 is (a + b)² = (a + b)(a + b)
