Question

Factor of x²-y² is________​

Answer 1

$\huge \mathsf \green{Answer}$

x² − y² = ( x − y ) ( x + y )

When multipled ( x − y ) by ( x + y ) then the terms in xy cancel out, leaving x² − y²

( x − y ) ( x + y ) = x² + xy − yx − y²

= x² + xy − xy − y² =

x² − y²

Answer 2

solution↓

• we know that

• $a {}^{2} - b {}^{2} = (a + b)(a - b)$
• comparison a=x and b=y

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

________________________________

factorise

• $= (x + y)(x - y)$
