Question

what is the factorisation of x^2-25y^2 ​

Answer 1

Answer:

James Rennell

Mapping India during the Colonial Period. The Survey of India was started by James Rennell, the first Surveyor General of Bengal (Phillimore 1945).

Answer 2

Step-by-step explanation:

$Rewrite  \: 25y225y2 \:  as \green(5y)2(5y)2.x2−(5y)2$

Since both terms are perfect squares, factor using the difference of squares formula,

Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) where a=x and b=5y.(x+5y)(x−(5y))
