Question

Factorise= 25x²-64y². [5 Star+brainnliest.]

Answer 1

Hey !

Here is your answer !!

____________________

➡ 25x^2 - 64y^2

➡ ( 5x )^2 - ( 8y )^2

Using ---> a^2 - b^2 = ( a + b ) ( a - b )

Hence your answer

➡( 5x + 8y ) ( 5x - 8y )

Hope it helps !!

Answer 2

Hiiii. .....friends

The answer is here,

$= > \: 25 {x}^{2} - 64 {y}^{2}$

$= > \: {(5x)}^{2} - {(8y)}^{2}$

This is in the form of ,

$= > \: {a}^{2} - {b}^{2} = (a + b)(a - b)$

$= > \: (5x + 8y)(5x - 8y)$

:-)Hope it helps u
