Add :-

3m²(7 - 2m) + 2m(3m² - 5m)

\LARGE{\sf{\underline{\underline{Solution:-}}}}

3m²(7 - 2m) + 2m(3m² - 5m)

Firstly, let us do the multiplication:

⟹ 21m² - 6m³ + (6m³ - 10m²)

⟹ 21m² - 6m³ + 6m³ - 10m²

Now, place the like terms together:

⟹ 21m² - 10m² - 6m³ + 6m³

- 6m³ and 6m³ will be cancelled.

⟹ 21m² - 10m²

⟹ 11m²

\LARGE{\sf{\underline{\underline{Required \ Answer:-}}}}

By adding 3m²(7 - 2m) + 2m(3m² - 5m),

we will get 11m²

Question :

ㅤㅤㅤㅤㅤㅤ

Add 3m²(7 - 2m) + 2m(3m²-5m)

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

Solution :

ㅤㅤㅤㅤㅤㅤ

 \tt {(3m)^2 (7 - 2m) + 2m(3m^2 - 5m) }

ㅤㅤㅤㅤㅤㅤ \small \mathfrak \pink {\underline {Multiplying \: the \: eq :}}

ㅤㅤㅤㅤㅤㅤ

 : \implies \tt { 21m^2 - 6m^3 + 6m^3 - 10m^2 }

ㅤㅤㅤㅤㅤㅤ

ㅤㅤㅤ : \implies \tt {22m^2 - 10m^2}

ㅤㅤㅤㅤㅤㅤ

ㅤㅤㅤ ㅤ : \implies \tt {11m^2}
