Question

expand using identity q^4 - 625p ^4​

Answer 1

Answer:

q⁴-625p⁴

=q⁴-(5p)⁴

=(q²)²-{(5p)²}²

=(q²+25p²)(q²-25p²)

=(q²+25p²)(q+5p)(q-5p)

Answer 2

Answer:

(q^2+25p^2)(q+5p)(q-5p)

Step-by-step explanation:

Using identity : a^2-b^2=(a+b)(a-b)

q^4-625p^4

(q^2)^2-(25p^2)^2

= (q^2+25p^2)(q^2-25p^2)

= (q^2+25p^2)(q+5p)(q-5p)
