Question

Fatore as expressões (fator comum):

Exemplo:

a) 2x+2y= 2(x+y)

b) 7a²-35

c)10x²-4y

d) am-4ac

e) x²+15x

f) 6m³-m²


      8    5
g) 6a-12a

h) x²-x7+xz

Answer 1

a) 2x+2y= 2(x+y)

b) 7a²-35 = 7(a² - 5)

c)10x²-4y = 2(5x² - 2y)

d) am-4ac = a(m - 4c)

e) x²+15x = x(x + 15)

f) 6m³-m²  = m²(6m - 1)

g) 6a-12a = 6a(1-2) = -6a

h) x²-x7+xz = x(x - 7 + z)

ou

x²-x⁷+xz = x(x - x⁶ + z)
