Question

( x + 5 ) ( x - 2 ) = ( x + 3 ) ( x + 4 )

Answer 1

Respuesta:

$- \frac{11}{2}$

Explicación paso a paso:

$( x + 5)( x - 2) = ( x + 3)(x + 4) \\ x {}^{2} - 2x + 5x - 10 = x {}^{2} + 4x + 3x + 12 \\ - 2x - 5x - 4 x - 3x = 12 + 10 \\ - 4x = 22 \\ x = \frac{22}{ - 4} \\ x = - \frac{11}{2}$
