Question

5xy³ + 20x³ -6a²y³ – 24a²x² = agrupamento
49X³a +35bx +77x²a³ +55a²b= agrupamento

Answer 1

a) 5xy³ + 20x³ - 6a²y³ - 24a²x²

5x × (y³ + 4x²) - 6a² × (y³ + 4x²)

(y³ + 4x²) × (5x - 6a²)

b) 49x³a + 35bx + 77x²a³ + 55a²b

7x × (7x²a + 5b) + 11a² × (7x²a + 5b)

(7x²a + 5b) × (7x + 11a²)

(7ax² + 5b) × (7x + 11a²)
