Answer 1

1) (x + 2)² – 49 = (x + 2)² – 7² = (x + 2 – 7)(x + 2 + 7) = (x – 5)(x + 9)

2) (x – 10)² – 25y² = (x – 10)² – (5y)² = (x – 10 – 5y)(x – 10 + 5y)

3) 25 – (y – 3)² = 5² – (y – 3)² = (5 – y + 3)(5 + y – 3) = (8 – y)(2 + y)

4) (a – 4)² – (a + 2)² = (a – 4 – a – 2)(a – 4 + a + 2) = –6(2a – 2) = 12 – 12a

5) (m – 10)² – (n – 6)² = (m – 10 – n + 6)(m – 10 + n – 6) = (m – n – 4)(m + n – 16)
