Coefficient of x^2 in expansion of the binomial theorem (2x-1)^4 show your work

24

Step-by-step explanation:

If you use Pascal's triangle, which I did, you will look at the 5th row of the triangle which contains the numbers 1, 4, 6, 4, 1

If we expand using a = 2x and b = -1, then the expansion looks like this:

If you simplify all that down by multiplying, you'll get

If you don't know how to use Pascal's triangle, you need to learn.  It's so very cool!
