8x² + 6x + 1. This is a quadratic equation as the highest power of x is to the power of 2.A quadratic is written in the form: ax² + bx + c. The coefficient of the x² term ...

So what we need to do is work out what x is when y is equal to 11.Firstly, we would rearrange the equation so that x is the subject and to do this we subtract 5 from both sides.Thisgives us y-5 =2x. Divid...

For most Quadrátics in the form of ax^2+bx+c=0there is atleast 2 solutions in most cases as the graph of the quadratic passes the x axis on most cases. But In some cases the quadratic graph doesn’t Cross ...
