$(m-2)^{2} = m^{2} - 4m + 4\\\\(x-3)^{2} = x^{2} - 6x + 9\\\\\ (7-m)^{2} = m^{2} - 14m + 49 \\\\\ (y-6)^{2} = y^{2} - 12y +36\\\\\ (a+\frac{1}{3} )^{2} = a^{2} + \frac{2}{3} a + \frac{1}{9} \\\\(b+\frac{1}{2} )^{2} = b^{2} +b+\frac{1}{4}$

arturugaj3gmailcom: а можно конкретнее

sonbaro: 1 формула (a-b)^2 = a^2 - 2ab + b^2

sonbaro: 2 формула (a+b)^2 = a^2 + 2ab + b^2

arturugaj3gmailcom: а спасибо просто у меня наверно телефон умер.. прости

sonbaro: всё в порядке, обращайтесь
