Simply the equation. y = x√x is the same as y = x3/2. This is because the square root of any articular number is the same as saying that number raised to the power half. Now to do x1...
Factorising is a way of simplifying an equation by putting it into common parts. In the equation above we can see that x is common to both the 5x^2 and the 20x. If we divide by x and put this in-front of ...
First, notice that any equation crosses the x-axis when y = 0.Second, notice that x2 + x - 2 = 0 is an example of a quadratic equation. So, we generally do 1 of 3 things (Factorise, Complete th...
To prove (x+2) is a factor, the value of x that makes x+2 equal 0 must be substituted into the function g(x) also making g(x)=0. In this case, the value of x being -2 makes x+2 equal to 0 and when substit...
