You choose 10C3 but I believe that should be (10C4)(3)^7(-7x)^3 which would be -157529610x^3 which means the coefficient is -157529610 please check it as soon as possible

How could I find the value of b by the expression (1+ax)^n, which the expansion is 1-12x+90x^2+bx^3?

Is it 10 choose 3 because thats the power you are looking for or is that just a coincidence, if not, how did you know to do 10 choose 3
