Question

b) - 2x + 4)-(3x -8X)=

c) (x + 4)(x-4)=

c) (x + 4) (x - 4)=

d) (x-5) (x - 5)=

e) 2x + 4y - 6-3x-2y + 8 =

f) 6x - 7y + 2 - 8y + 9x - 12=

8) 7y - 3 +9y-2-=​

Answer 1

Resposta:

B) (- 2x + 4)-(3x -8X)=

-2x+4-(-5x)

-2x+4+5x

3x+4=

X=1,3

C)  (x + 4)(x-4)=

x²-4²

x²-16

d) (x-5) (x - 5)=

(x-5)¹x (x-5)¹

(x-5)¹⁺¹

(x-5)²

e) 2x + 4y - 6-3x-2y + 8 =

-x+2y+2

f) 6x - 7y + 2 - 8y + 9x - 12=

15x-15y-10

5(3x-3y-2)

8) 7y - 3 +9y-2-=​

8y-5
