Answer 1

1. 25p² - 1
2. 8a³ + 125

May God bless you

Answer 2

(i) (5p-1)^2

[ (a-b)^2 = a^2 + b^2 - 2ab ]

= (5p)^2 + 1^2 - 2×5p×1

= 25p^2 + 1 - 10p

(ii) (2a+5)^3

[ (a+b)^3 = a^3 + b^3 + 3ab(a+b) ]

= (2a)^3 + 5^3 + 3×2a×5(2a+5)

= 8a^3 + 125 + 30a(2a+5)

8a^3 + 125 + 60a^2 + 150a

here is your ans hope it's help.
