Question

Como se resuelve esto:
x²-{-3X+5-[-X+X(2-X)]}

Answer 1

Respuesta:

$4x - 5$

Explicación paso a paso:

$x {}^{2} - (3x + 5 - ( - x + x(2 - x))) \\ \\ x {}^{2} - (3x + 5 - ( - x + 2x - x {}^{2} )) \\ \\ x {}^{2} - ( - 3x + 5 - (x - x {}^{2} )) \\ \\ x {}^{2} ( - 3x + 5x + x {}^{2} ) \\ \\ x {}^{2} - ( - 4x + 5 + x {}^{2} ) \\ \\ x {}^{2} + 4x - 5 - x {}^{2} \\ \\ 4x - 5$
