Quadratic expressions

Here are some pointers to help you improve your mathematical skills.
Look at the example below:-
(3x-2)2
Now the common mistake is to do 9x-4 however this is incorrect.
when facing an equation such as this, here's the method you should use:-
the equation has to be split into 2.
(3x-2)2
(3x-2) (3x-2)
now that you have this you can do the equation using the method you want.
(3x-2) (3x-2)
9x2-6x-6x+4
this can then be simplified into 9x2-12x+4
*tadaa!*
and that's the way to tackle this type of equation!
