FACTORISE-:-:-:

1. 25a²b²- 49c²

By id. [ (x+y)(x-y) ] = [x²-y²]

=> (5ab+7c)(5ab - 7c)


2. p^8 - q^8

By id. [ (x+y)(x-y) ] = [x²-y²]

=>[p⁴+q⁴][p⁴-q⁴]


Be perfectionist

Heya mate,

Here is your answer,. ⬇️⬇️

${ANSWER :-}$

_________


$<i>$ a) 25a^2b^2 - 49c^2

= (5ab)^2 - (7c)^2

= (5ab + 7c) (5ab - 7c) ⬅️

b) p^8 - q^8

= (p^4 + q^4) (p^4 - q^4)

= (p^4 + q^4) (p^2 + q^2) (p^2 - q^2)

= (p^4 + q^4)(p^2 + q^2)(p+q)(p-q) ⬅️
