1. Berapakah nilai x dan y untuk persamaan 2x + y = 7 dan x – y = 1?

( x 3 + 6 ) ( x 4 − 9 ) = x 7 − 9 x 3 + 6 x 4 − 54 = x 7 + 6 x 4 − 9 x 3 − 54

To simplify ( x 3 + 6 ) ( x 4 − 9 ) , we expand it using the distributive property to obtain x 7 + 6 x 4 − 9 x 3 − 54 . The terms are arranged in descending order of their degree. Thus, the final answer is x 7 + 6 x 4 − 9 x 3 − 54 .
