ddd
Step-by-step explanation:
Divide 5a2 + 6a - 9 into 25a4 + 19a2 - a - 78.
5a^2 -6a +20
-------------------------------------------------
5a^2+6a-9 25a^4 + 0a^3 +19a^2 - 1a - 78
25a^2 + 30a^3 - 45a^2
------------------------------------------------(subtract)
-30a^3 +64a^2 -1a
-30a^3 -36a^2 +54a
-----------------------------------------------(subtract)
100a^2 -55a -78
100a^2 +120a - 180
------------------------------------------------------
- 175a +102
Quotient : 5a^2 -6a+20
Remainder : -175+102
