Question

3m²+8m-4 and 6m²-m+7

Answer 1

Given:

Two expressions:

• 3m² + 8m - 4
• 6m² - m + 7

What To Do:

We have to find the sum of the twp expressions.

How To Do:

• First, put them in brackets.
• Next, remove the brackets.
• Then, rearrange the like terms.
• Finally, solve the like terms.

Solution:

(3m² + 8m - 4) + (6m² - m + 7)

Remove the brackets,

⇒ 3m² + 8m - 4 + 6m² - m + 7

Rearrange the like terms,

⇒ 3m² + 6m² + 8m - m - 4 + 7

Solve the first terms,

⇒ 9m² + 8m - m - 4 + 7

Solve the second terms,

⇒ 9m² + 7m - 4 + 7

Solve the third terms,

⇒ 9m² + 7m + 3

∴ Therefore, the sum of the expressions is 9m² + 7m + 3.

Answer 2

Answer:

9m square + 7 m+ 3
