+8y and -8y cross out.

So the first one is 3x=15
Second one is 2x=10

x=5
Then plug x is one of the equations

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

tekilochka [14]

Answer:

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:

$1(2x)^4(-1)^0+4(2x)^3(-1)^1+6(2x)^2(-1)^2+4(2x)^1(-1)^3+1(2x)^0(-1)^4$

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

$16x^4-32x^3+24x^2-8x+1$

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