Question

RESOLVA
c) (4x²-y²)²
d) (1/3 - x elevado a sexta potência)²
e) (x/3 - 4/6)²

Answer 1

c) (4x² - y²)² =
    (4x²)² - 2.4x².y² + (y²)² = 16x⁴ - 8x²y² + y⁴

d) (1/3 - x⁶)² = 
    (1/3)² - 2. 1/3.x⁶ + (x⁶)² = 1/9 - 2x⁶/3 + x¹²

e) (x/3 - 4/6)² = 
     (x/3 - 2/3)² = [(x-2)/3]² = (x² - 4x + 4)/9
