ANSWERS :

(b)  (7x² - 7) - (x² + 7x - 7) - (5x² + x)

             = 7x² - x² - 5x² - 7 - 7 + 7x + x

             = x² - 14 + 8x

              x² + 8x - 14

(d) 2(3m - 2n) - 6(m - 2n)

             = 6m - 4n - 6m + 12n

             = 6m - 6m - 4n + 12n

            ⇒ 8n

(c) -c(c + a)

              -c² - ac

(b) x - 2y - [4x - y - {x - 2z -(x + 2y)}]

              = x - 2y - [4x - y- {x - 2z - x + 2y}]

              = x - 2y - [4x - y - x - 2z - x + 2y]

              = x - 2y - 4x - y - x - 2z - x + 2y

              = x - 4x - x - x - 2y + 2y - y - 2z

              = -5x - y - 2z

              -5x - 2z - y

(d) -m² - [m - {m² + 3m - (4m - m² - 2m - 3m²)}]

              = -m² - [m - {m² + 3m - 4m - m² - 2m - 3m²}]

              = -m² - [m - m² + 3m - 4m - m² - 2m - 3m²]

              = -m² - m - m² + 3m - 4m - m² - 2m - 3m²

              = -m² - m² - m² - 3m² - m + 3m - 4m - 2m

              -6m² - 4m

HOPE IT HELPS ...
