Explain to the students what a one to many functions is which in this case is a quadratic, giving them an understanding of why there are two solutions, aided with the image of the quadratic.

Firstly, we can divide through by 2 to get a simpler form of the equation: x^2-7x+6=0. To solve this quadratic equation we need to factorise it. We do this by splitting it up into two brackets which would...

Begin by factorisation: (3x+7)(2x-5) < 0 Then determine which values of x give 0 -7/3 and 5/2Draw a sketch of the graph Y intercept = -35Then determine where less than 0 - under x axis. Reach -7/3<x...

By noticing the the numerator (x^2 + 1) is similar to the derivative of the denominator (x^3 +3x +2) you can integrate the function by using natural logarithms, to form the logarithm ln( x^3 +3x +2). Howe...

First, let us separate the constant term and complete the square for (x^2 + 1x).
x^2 + x - 6 = (x^2 + x) - 6
Now, let us halve the coefficient of x.
0.5 of +1 = +0.5
Write (x )^2 with ...
