Step-by-step explanation:

= 27ab - 18a²

= 9a(3b - 2a)

Answer 2

Answer:

The factors of the expression $27ab-18a^{2}$ is $9a(3b-2a)$.

Step-by-step explanation:

Given : $27ab-18a^{2}$

To find : The factors of the above expression.

Solution :

• The given algebraic expression is,

          $27ab-18a^{2}$

• We have to find the factors of the above expression.
• To find the factors of given expression, we have to take out common factors from both the terms.
• The given expression is,  

          $27ab-18a^{2}$  

• $9a$ is common for both the terms, taking it out, we get

          $27ab-18a^{2} = 9a(3b-2a)$

• ∴ The factors of the expression $27ab-18a^{2}$ is $9a(3b-2a)$.
