Divide: \(a^{3x} – 26a^{2x} + 156a^{x} – 216\) by \(a^{2x} – 24a^{x} + 108\).
-
ax - 2
- ax + 2
- ax - 8
- ax - 6
The correct answer is: A
Explanation
\(\frac{a^{3x} - 26a^{2x} + 156a^{x} - 216}{a^{2x} - 24a^{x} + 108}\)
Let \(a^{x} = z\)
\(\therefore = \frac{z^{3} - 26z^{2} + 156z - 216}{z^{2} - 24y + 108} ... (i)\)
Dividing (i) above, we get \(z - 2\)
= \(a^{x} - 2\)
