Question

Gnt me ajudem pfvr!! Obgd, precisa de cálculo.
1) fatore as expressões
a) 4x⁴-5x³+6x²:
b) 8a²b²-4ab+12a³b³:
c) 5b+5c+ab+ac:
d) am+bm++an+bn+cn:
e) m²-12m+36:
f) 4x²-16y²:

Answer 1

a)
4x⁴ - 5x³ + 6x² =
x² * (4x² - 5x + 6)

b)
8a²b² - 4ab + 12a³b³ =
4ab * (2ab - 1 + 3a²b²)

c)
5b + 5c + ab + ac =
5 * (b + c) + a * (b + c) =
(b + c) * (5 + a)

d)
am + bm + cm + an + bn + cn =
m * (a + b + c) + n * (a + b + c) =
(a + b + c) * (m + n)

e)
m² - 12m + 36 =
(m - 6) * (m - 6) =
(m - 6)²

f)
4x² - 16y² =
4 * (x² - 4y²)
