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)...
First draw the triangle and label all the information you have as well as the unknown angle or side length. There should be at least one angle labelled with some informtion - use this angle to label the o...
This question is about multiplying two brackets together. There are two parts to each bracket: x, +3 and x, +5. The parts in the first b...
