Question

what mist be added to 10a²b + 8ab² -8a³b³-b⁴ to get 5a²b - 6ab²- 7a³b³​

Answer 1

Answer:

Step-by-step explanation:

Let A must be added to get 5a²b - 6ab²- 7a³b³​

10a²b + 8ab² -8a³b³-b⁴ +A = 5a²b - 6ab²- 7a³b³​

                                        A = (5a²b - 6ab²- 7a³b³​) - (10a²b + 8ab² -8a³b³-b⁴)

                                        A = 5a²b - 6ab²- 7a³b³​ -  10a²b - 8ab² + 8a³b³ + b⁴

                                        A = 5a²b - 10a²b - 6ab² - 8ab²- 7a³b³​+ 8a³b³+ b⁴

                                        A = - 5a²b -14ab² + a³b³ + b⁴

Thank you.
