Thank f*** the only people who need to know this are people willing to teach it to others in their lives...
Nope.Chris Dale said:Very easy i learnt that in year 8
I just used (x+a)^2=(x^2+2ax+a^2)
x^2+6x+9

Not as easy but still not in my opinion hardBurst6 said:FIND THE ROOTS OF x^3-64.
x^3-64
(x-4)(x^2-4x+16)
(x-4)((x-2)^2+16-4)
(x-4)(x-2+√12)(x-2-√12)
By the way I am an Australian year 12 student studying advanced mathematics(eg. Complex number, Advanced Calculus, etc.)

FOIL: (x+3)^2
EDIT: FOIL also means Expand...
The correct answer is{x^2+6x+9}
