Question

Factorise
(3x – 4y)^2 – 25z^2​

Answer 1

Answer:

(3x−4y+5z)(3x−4y−5z)

Step-by-step explanation:

=Using, a^2-b^2=(a+b)(a−b)

=(3x-4y)^2-(5z)^2

=(3x−4y+5z)(3x−4y−5z)

Answer 2

Answer:

(3x−4y+5z)(3x−4y−5z)

Step-by-step explanation:

(3x-4y)^2-(5z)^2

(3x−4y+5z)(3x−4y−5z)

Hint:-using the property a^2-b^2=(a+b) (a-b)
