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

How can you divide an algebraic expression by another algebraic expression?


Why is it that when 'transformation A' is followed by 'transformation B', that the combined transformation is BA and not AB?


l1 and l2 are tangents of a circle. l1 intersects the circle at (3-√3,5) with a gradient of √3, and l2 intersects the circle at (3+√2,4+√2) with a gradient of -1. Find the centre of the circle, and hence find the radius of the circle.


What is the range of solutions for the inequality 2(3x+1) > 3-4x?
