Answer:
The coefficient of the fifth term is 126.
Step-by-step explanation:
The question implies that after the expansion of , what would be the coefficient of the fifth term. This long expansion can be easily done by the application of the Pascal principle of expansion.
Thus,
=
+
+
+
+
+
+
+
+
+
So, from this expansion, the fifth term is . And its coefficient is 126.
Answer:
If you expand this using pascals triangle you will see that the fifth term is 126a^5b^4
the coefficient is the number 126
Please help, I have never been able to work these out although there so simple .-.
Answer:
9 or -6
Step-by-step explanation:
To solve, I would suggest factoring.
You need to find two numbers which can be multiplied for 54 and also combined in some way to get 3. In this case, 9 and 6 are perfect.
Next, you can set both of your terms equal to zero to find your possible solutions.
