Question

( x + 4)(x + 5)=
(y – 6) (y – 8)=
(x + 2) (x – 4)=
(x + 5) (x + 5)=
(x – 6) (x – 6)=

Answer 1

( x + 4)(x + 5)=( x + x)(4 + 5) = 2x =9 = x=9-2=7

(y – 6) (y – 8)=(y – y) (6 – 8)=x =2

(x + 2) (x – 4)=(x - x) (2 + 4)=x=6

(x + 5) (x + 5)=(x + x) (5 + 5)=2x =10

(x – 6) (x – 6)=(x + x ) (6+ 6)=2x= 12=x=12-2=10

Answer 2

Respuesta:

( x + 4)(x + 5)=( x + x)(4 + 5) = 2x =9 = x=9-2=7

(y – 6) (y – 8)=(y – y) (6 – 8)=x =2

(x + 2) (x – 4)=(x - x) (2 + 4)=x=6

(x + 5) (x + 5)=(x + x) (5 + 5)=2x =10

(x – 6) (x – 6)=(x + x ) (6+ 6)=2x= 12=x=12-2=10
