Question

ME AJUDEM PF URGENTE EMPLOROO

Fatore as Expressões :
a) 7bx+x+7by+y =

b) 2a²+4ab+ba+2b² =

c) x²-25 =

d) 81x²-1 =

e) a²64b² =

Answer 1

a)
= 7bx + x + 7by + y
=x(7b + 1) + y(7b + 1)
= (x + y).(7b + 1)
--------------------------------------------------
b)
= 2a² + 4ab + ab + 2b²
= 2a(a + 2b) + b.(a + 2b)
= (2a + b).(a + 2b)
--------------------------------------------------
c)
= x² - 25
= (x + 5).(x - 5)
--------------------------------------------------
d)
= 81x²-1
= (9x + 1).(9x - 1)
-------------------------------------------------
e)
= a² - 64b²
= (a + 8b).(a - 8b)
