What should be subtracted from 3a² - 4b²+ 5ab to obtain - a²- b² + 6ab?​

Answer»

ANSWER:

To GET the answer we must add 3a² - 4b²+ 5a with  - a²- b² + 6ab

Hence  3a² - 4b²+ 5ab + - a²- b² + 6ab = 2a^{2} + 11AB - 5b^{2}

So 2a^{2} + 11ab - 5b^{2} should be SUBTRACTED from 3a² - 4b²+ 5a to get - a²- b² + 6ab

Hope it helps
