Expand (2x+3)^4

We will you use Pascal's triangle in order to find coefficients:         1        1  1       1 2 1     1 3  3 1    1  4  6  4  1 so, our coefficients will be 1,4,6,4,1 now, let's expand: (2x+3)4=(2x)4+4*(2x)33+6(2x)232+4(2x)*33+34=16x4+96x3+216x2+216x+81 (2x+3)4=116x4+96x3+216x2+216x+81
