what do i do?

anonymous · Answer

okay @asnaseer

parthkohli · Answer

Don't use FOIL, I've got a method which has the same concept.
$\Rightarrow (x - 3)(x - 3) = x(x - 3) - 3(x - 3) $
Might help if you are familiar with distributive property.

asnaseer · Answer

@ParthKohli that method is also described on the link I gave - page 3

You can even memorize  this identity $$\Large (a-b)^2 = (a)^2 -2(a)(b) + (b)^2$$

anonymous · Answer

@Luis_Rivera I wrote you a testimonial after I fanned you.

anonymous · Answer

x^2-6x+9 is correct... by using (a-b)^2=a^2-2ab+b^2 where a=1,b=6 and c=9.
