How do you solve quadratic equations?



By putting all the terms to one side with the other side =0
then by
factorising, or
completing the square method
or by using the quadratic formula.

Ok, since you got back to me I will try to be more helpful.
Maybe try these, you can do them just with normal factorising. That is how I want you to do them.

1) x 2 + 9x = -20

2) x2 -1x - 8 = x

3) 2x 2 + 15 = -13x

If you find Q3 difficult i will show you an easy (well, probably easier anyway) way to do it.
If you have problems I will show you how it is done. If you post your work, just copy my equations and insert your working underneath so that it all stays together.
