Question

simplify (3a²-b²+2ab)-(a²+b²+ab)​

Answer 1

Answer:

(3a²-b²+2ab)-(a²+b²+ab)​

= 3a² - b² +2ab - a² - b² - ab

= 2a² - 2b² + ab

Answer 2

$(3a^{2} - {b}^{2} - 2ab) - ( {a}^{2} + {b}^{2} + ab) \\ = 3a^{2} - {b}^{2} - 2ab - {a}^{2} + {b}^{2} + ab \\ = 3a^{2} - {a}^{2}- {b}^{2} + {b}^{2} - 2ab + ab \\ = 2 {a}^{2} - ab$
