STILL CORRECT 2022! :D
q^2 - 12q + 36.
36 = (-4)*(-9) = (-6)*(-6).
Choose a pair of factors whose sum = B = -12:
(q-6)*(q-6).
Use algebraic formula:
( a ± b )² = a² ± 2 ∙ a ∙ b + b²
This mean:
( a + b )² = a² + 2 ∙ a ∙ b + b²
( a - b )² = a² - 2 ∙ a ∙ b + b²
so:
a² - 2 ∙ a ∙ b + b² = ( a - b )²
q² - 12 q + 36 = q² - 2 ∙ q ∙ 6 + 6² = ( q - 6 )²
