Question

4x^2 - x^2 - 2xy - y^2​

Answer 1

Explicación paso a paso:

$4 {x}^{2} - {x}^{2} - 2xy - {y}^{2}$

$4 {x}^{2} - ( {x}^{2} + 2xy + {y}^{2} )$

$4 {x}^{2} - (x + y) ^{2}$

$(2x - (x + y)) \times (2x + (x + y)$

$(2x - x - y) \times (2x + (x + y))$

$(2x - x - y) \times (2x + x + y)$

$(x - y) \times (2x + x + y)$

$( x - y) \times (3x + y)$
