P(x)=2x² +3x + 2​

Answer 1

Verified answer

Respuesta:

11

Explicación paso a paso:

P ( x ) = 2x² + 3x + 2

P ( 1 ) = 2 ( 1 )² + 3 ( 1 ) + 2

= 2 ( 1 ) + 3 + 2

= 2 + 3 + 2

P ( 1 ) = 7

P ( - 2 ) = 2 ( - 2 )² + 3 ( - 2 ) + 2

= 2 ( 4 ) - 6 + 2

= 8 - 6 + 2

= 8 + 2 - 6

= 10 - 6

P ( - 2 ) = 4

P ( 1 ) + P ( - 2 )

= 7 + 4

= 11
