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

(2x-14y).(2x+14y)=

Produtos notaveis​

Answer 1

Resposta:

(x-6).(x+6)

x²+6x-6x-36

x²-36

(2x-14y).(2x+14y)

4x²+28xy-28xy-196y²

4x²-196y²

Answer 2

A)
(x-6).(x+6)
= x^2 - 6^2
= x^2 - 36

Ou:
= x^2 + 6x - 6x - 36
= x^2 - 36
__________
B)
(2x - 14y).(2x + 14y)
= (2x)^2 - (14y)^2
= 4x^2 - 196y^2
