(y+m)2
(x-y)2
(m-b)2
(c-y)2
(h-x)2
(z+b)2
(f-x)2

Answer 1

(t - x)² = t² - 2tx + x²

(k + b)² = k² + 2bk + b²

(a + m)² = a² + 2am + m²

(h - p)² = h² - 2hp + p²

(y - b)² = y² - 2by + b²

(k + m)² = k² + 2km + m²

(f - h)² = f² - 2fh + h²

(a + r)² = a² + 2ra + r²

(y - b)² = y² - 2by + b²

(a + c)² = a² + 2ac + c²

(y + m)² = y² + 2my + m²

(x - y)² = x² - 2xy + y²

(m - b)² = m² - 2bm + b²

(c - y)² = c² - 2cy + y²

(h - x)² = h² - 2hx + x²

(z + b)² = z² + 2bz + b²

(f - x)² = f² - 2fx + x²

Так надо было сделать?
