x=-1/2 and x=1

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...

An example of an application of factorising quadratics is to find the unknown in the equation, x. Factorising means writing the above equation in the form (x+a)(x+b)=0 Using FOIL (First, Outer, Inner, Las...

Considering that: 9=3^2. We get: 9^(x+1)=3^2*(x+1)= 3^(2x+2).

We thus solve x^2-5x+2=2x+2

which is x=0 and x=7

it will be demonstrated with more detail during the session 

Conversion of trigonometric functions:

cos(30°) = √3 / 2

tan(60°) = √3

Computing equation with trigonometric substitutions:

12 cos(30°) - 2 tan(60°) = 12 (√3 / 2)...
