Question

can u solve this all of them thank you

Answer 1

1. = (a)^2-(5)^2 = (a+5)(a-5)

2. = (3x)^2-(8)^2 = (3x+8)(3x-8)

3. = (6a)^2-(1)^2 = (6a+1)(6a-1)

4. = (7m)^2-(11n)^2 = (7m+11n)(7m-11n0)

5. = (10)^2-(m^3n^3)^2 = (10+m^3n^3)(10-m^3n^3)

(x+2)^2-(y+1)^2 = (x+2+y+1)(x+2-y-1)

= (x+y+3)(x-y+1)
