Question

1. FACA A FATORAÇAO
a ) y² - 64
b ) 81x² - 36
c ) x² + 8x +16
d ) 2mx - 2my + 3nx - 3ny e ) 9x² - 12x + 25
f ) 3a² + a³ - 5a​

Answer 1

a ) y² - 64 = (y-8)(y+8)

b ) 81x² - 36 = (9x-6)(9x+6)

c ) x² + 8x +16 = (x+4)²

d ) 2mx - 2my + 3nx - 3ny =

2m(x-y)+3n(x-y)

(x-y)(2m+3n)

e ) 9x² - 12x + 25 = ?

f ) 3a² + a³ - 5a = a(3a+a²-5)
