(b-1)(b+6)=0b= 1 and -6Positive Solution = 1

A stationary point is a point where dy/dx = 0.First we need to find dy/dx. This is done by differentiating y term by term to get dy/dx = 3x^2 - 6x - 9.Setting this equal to zero, we need to solve 3x^2 - 6...

rearrange by taking away 2 and adding 1

The first thing that is important to understand that a graph essentially highlights every single possible value (for both x and y) within a given rangeWhat does this mean?This means that a line representi...

x² + 14x + 22 = 4x -2
1) First you should arrange the equation into the format ax² + bc + c = 0. This gives x² + 10x + 24 =02) Factorise into (x+n)(x+m) = 0. To work...
