Question

a2-2a-b2+2b please solve this equation. Thanks

Answer 1

Step-by-step explanation:

a² - 2a - b² + 2b

= a² - b² - 2a + 2b

= a² - b² - 2 (a - b)

= (a + b) (a - b) (a - b) - 2

= (a - b)² (- 2a - 2b)

Answer 2

this is your answer

${a}^{2} - {b}^{2} - 2a + 2b \\ = {a}^{2} - {b}^{2} - 2a + 2b \\ = (a - b)(a + b - 2) \\ = (a - b)(a + b - 2)$

your answer
