Question

factorise (16x power 2 -25y power 2)​

Answer 1

Answer:

The given expression is factorized in the uploaded photo.

Some more factorisation identities-

${x}^{2} + 2xy + {y}^{2} = {(x + y)}^{2} \\ {x}^{2} - 2xy + {y}^{2} = {(x - y)}^{2} \\ {(x}^{2} - {y}^{2}) = (x + y)(x - y)$

Answer 2

first u have to do there square root and then use the formula a^2-b^2=(a+b)(a-b)

Hope it will help...
