s of a. Divide 5a^2 + 6a - 9 into 25a^4 + 19a^2 - a - 78.
1 answer:
Step-by-step explanation:
(25a^4 + 19a^2 - a - 78) : (5a^2 + 6a - 9) = 5a^2 - 6a + 20 Rest -175x + 102
25a^4 + 30a^3 - 45a^2
———————————————————————————————————————
- 30a^3 + 64a^2 - a - 78
- 30a^3 - 36a^2 + 54a
————————————————————————————————
100a^2 - 55a - 78
100a^2 + 120a - 180
—————————————————————
- 175a + 102
