Answer:
2a^2+a
Step-by-step explanation:
This is an algebra. An algebra is an expression with no equality sign, and it will be expressed till the simplest form.
(6a^2+3a) - (4a^2 + 2a)
Remove the brackets
6a^2+3a-4a^2-2a
6a^2-4a^2+3a-2a
2a² + a ( or a(2a+1) )
(6a²+3a) - (4a² + 2a) (expand parentheses)
= 6a²+3a - 4a² - 2a (group like terms)
= 6a²- 4a²+3a- 2a
= 2a² + a
= a(2a+1)
