Question

Fatore a expressão a seguir
4-x²-2x³-x⁴​

Answer 1

$4 - {x}^{2} - {2x}^{3} - {x}^{4}$

$4 - ( {x}^{2} + {2x}^{3} + {x}^{4} )$

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

$(2 - (x + {x}^{2} )) \times (2 + (x + {x}^{2} ))$

$(2 - x - {x}^{2} ) \times (2 + x + {x}^{2} )$

$( - {x}^{2} - x + 2) \times (2 + x + {x}^{2} )$

$( { - x}^{2} + x - 2x + 2) \times (2 + x + {x}^{2} )$

$( - x \times ( x - 1) - 2(x - 1)) \times (2 + x + {x}^{2} )$

$- (x + 1) \times (x + 2) \times (2 + x + {x}^{2} )$
