Fill in the blanks to make the statements true:
Factorised form of 18mn + 10mnp is ……… .

2mn(9 + 5p)

The irreducible factors of 18mn and 10mnp are

18mn = 2×3×3×m×n

10mnp = 2×5×m×n×p

Here, the common factors of the two terms are 2mn. So the factorization of 18mn + 10mnp will be

18mn + 10mnp = (2×3×3×m×n) + (2×5×m×n×p)

= (2mn×9) + (2mn×5p)

= 2mn(9 + 5p)
