Question

divide the following polynomials, then place the answer in the proper location on the grid. Write the answer in descending powers of a. Divide 5a^2 + 6a - 9 into 25a^4 + 19a^2 - a - 78.

Answer 1

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
