Answer 1

Answer:

Given to add the terms :-

6a² - b² + 5b² - a² + 7a² + b² - 5b² + a²

Concept to know :-

For adding the algebraic terms, we have to add only like terms. We cannot add the unlike terms.

Solution :-

Step :- 1

First write the given question.

6a² - b² + 5b² - a² + 7a² + b² - 5b² + a²

Step :- 2

Identify the like terms.

• 6a² , -a² , 7a² , a² with respect to variable a².
• -b² , 5b² , b² , -5b² with respect to variable b².

Step :- 3

Keep aside the terms.

6a² - a² + 7a² + a² - b² + 5b² + b² - 5b²

Step :- 4

Now add the terms.

6a² + 7a² + a² - a² + 5b² + b² - 5b² - b²

14a² - a² + 6b² - 6b²

13a² + 0  

13a²

So, the value of 6a² - b² + 5b² - a² + 7a² + b² - 5b² + a² is 13a².

Answer: 13a²
