Question

Ayúdenme jajska (x + 6) (x4)+
(x+2)(x-2)= x²-4​

Answer 1

Respuesta:

5x² + 24x - 4

Explicación paso a paso:

(x + 6) (x4)+ (x+2)(x-2)= x²-4​

( x + 6 ) ( x . 4 ) + ( x + 2 ) ( x - 2 )

= ( x + 6 ) x.4 + ( x + 2) ( x - 2 )  

= 4x ( x + 6 ) + ( x + 2 ) ( x - 2 )

 x.4 ( x + 6 ): 4x² + 24x

= 4x² + 24x + ( x + 2 ) ( x - 2 )

( x + 2 ) ( x-  2 ): x² - 4

= 4x² + 24x + x -4

Simplificar: 4x² + 24x + x² - 4  

= 5x² + 24x - 4
