Hey.
I am having difficultly with two math problems:
1. In the expansion of (mx+n)^5 the numerical coefficient of the second term is -48 and of the third term if 28.8 Find the values of m and n.
2. The first three terms in the expansion of (1+a)^n are 1-18+144. Determine the values of a and n
Could someone please explain to me how to do these? Thanks.
