= (x + 8)(c + d)

= (x - 8)(c + d)

= (x + 8)(c - d)

= (x - 8)(c - d)

= (x - 4)(c + 4)

= (x + 4)(c + 4)

= (x + 4)(c - 4)

= (x - 4)(c - 4)

= (y + 3)(y³ - 1)

= (y - 3)(y³ + 1)

= (y - 3)(y³ - 1)

= (y + 3)(y³ + 1)

= (x - b)(a + b)

= (x - b)(a - b)

= (x + b)(a - b)

= (x + b)(a + b)

=( a²+1)(a⁴-3)

= ( a²+1)(a⁴+3)

= ( a²-1)(a⁴+3)

= ( a²-1)(a⁴-3)

= (m² - n)(a - b -c)

= (m² - n)(a + b -c)

= (m² - n)(a - b +c)

=(m² + n)(a - b -c)
