Expand the expression using the Binomial Theorem:
(3x + −1)^5 =

Step-by-step explanation:

The binomial theorem is .

Using the sequence, we can calculate the coefficients for each value to arrive at the final result. I personally used a calculator but the values can be calculated by hand as well.

step-by-step explanation:

if x = 2 you have to find x to finish the problem

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
