difference of 2 squares when you see things that look like that, square root both sides and make one positive one negative

e.g. 9x²-4

sqrt the magnitudes (dont sqrt -4 that gets you 2i which is a completely different thing)
sqrt 9x² = 3x
sqrt 4 = 2

do factors on both sides make one the real conjugate of the other

∴ answer is (3x+2)(3x-2)

DOTS is relatively complex for a 6th grader.

4x²-12x = 0

the way you would have to do it would be

(2x+root12)(2x-root12)

i was assuming she was learning dots but that is also a credible answer

x would = o and x would = 3 in that respect
