Question

3. Simplify (2 x + a)(2x + a) - 4x² - a²​

Answer 1

Answer:

-2x² + 4ax

Step-by-step explanation:

(2x + a)(2x + a) - 4x² - a²​                    Simplify the bracket first

2x² + 2ax + 2ax + a² - 4x² - a²​

2x²- 4x²+ 2ax + 2ax + a²- a²

-2x² + 4ax                                          Cannot be simplified further
