Question

Write all factors of the terms:

a) -4xy + 6

b) 5ab2

- 9a2b

c) -mn + 3n2 – 4m2​

Answer 1

Answer:

a) -4xy + 6

-4xy = -2×2×x×y

6= 3×2

Factors = 3×2×x×y = 6xy

b) 5ab² - 9a²b

5ab² = 5×a×b×b

-9a²b = -3×3×a×a×b

Factors = 5×-3×3×a×b = -45ab

c) -mn + 3n2 – 4m2

-mn= -m×n

3n²= 3×n×n

-4m²= -2×2×m×m

Factors= -m×n×3×n×n×-2×2×m×m = 12m³n³
