This resource is a comprehensive overview of everything students and teachers alike need to know regarding binomial expansion in accordance with the A-Level Mathematics specification. It can either be used by teachers to guide students through lessons or by students as a revision resource. Tes paid...
The power that we are expanding the bracket to is 3, so we look at the third line of Pascal’s triangle, which is 1 3 3 1. So the answer is: 33+ 3 × (32× x) + 3 × (x2× 3) + x3(we are replacing a by 3 and b by x in the expansion of (a + b)3above) Genera...
