Question

Binomio con termino comun = trinomio de la forma x2 + bx +c

(a + b) (a + c) =

(x - 4) (x + 6)=

(x + 8) (x - 5)=

(w - 2) (w - 8 )=

(a - 5) (a + 4) =

(x - 9) (x + 6)=

(x + 8) (x - 1)=

(w - 2) (w - 4 )=

​

Answer 1

Respuesta:

a + b) (a + c) = a^2 + ( b+c)a + ac

(x - 4) (x + 6)=   x^2 + 2x - 24

(x + 8) (x - 5)=  x^2 +3x -40

(w - 2) (w - 8 )=  w^2 - 10w + 16

(a - 5) (a + 4) = a^2 - a -20

(x - 9) (x + 6)=  x^2 - 3x  - 54

(x + 8) (x - 1)=  x^2 + 7x - 8

Explicación paso a paso:

a + b) (a + c) = a^2 + ( b+c)a + ac

(x - 4) (x + 6)=   x^2 + 2x - 24

(x + 8) (x - 5)=  x^2 +3x -40

(w - 2) (w - 8 )=  w^2 - 10w + 16

(a - 5) (a + 4) = a^2 - a -20

(x - 9) (x + 6)=  x^2 - 3x  - 54

(x + 8) (x - 1)=  x^2 + 7x - 8
