x=-1/2 and x=1

General form of a Geometric series: a + ar + ar^2 + ar^3 + ar^4 + … First three terms: 10 + 100.2 + 100.2^2 = 10 + 0.2 + 0.04Nth Term of a Geometric Series: ar^n-1 where there are n terms Proof o...

Firstly I would try to learn about the students abilities and maybe do an easier linear equations (without brackets) to ensure they have a basic idea how to solve these types of equations. For this questi...

There are three simple steps to prove anything by induction.

Step 1: When n=1

1²=1

then: 1/6 x 1x (1+1) x (2+1)

=1x2x3/6 =1

Therefore it is true for n=1 

We first notice that the degree of the numerator is the same as the degree of the denominator so we have an improper fraction which we need to separate into an integer and a proper fraction before we can ...
