Answer 1

a² - b² = (a + b)(a - b)

(2x)² - 1 = (2x + 1)(2x - 1)

4y² - 9 = (2y)² - 3² = (2y + 3)(2y - 3)

z² - (1/4) = z² - (1/2)² = (z + 1/2)(z - 1/2)

x² - y² = (x + y)(x - y)

4p² - 16 = (2p)² - 4² = (2p + 4)(2p - 4)

m² - (n + 1)² = ( m - n - 1)(m + n + 1)

(p + 1)² - q² = (p + 1 - q)(p + 1 + q)

y² - 1/9 = y² - (1/3)² = (y + 1/3)(y - 1/3)

(x/2)² - 1 = (x/2 + 1)(x/2 - 1)
