Question

EXERCISE 5.2
1. Add the following algebraic expressions (b) 8p^2q^2, -5p^2,3p^q^2,-p^2q^2​

Answer 1

Given:

• 1st expression: 8p²q²
• 2nd expression: -5p²
• 3rd expression: 3pq²
• 4th expression: p²q²

What To Do:

We have to add and find the sum the above expressions.

Solution:

(8p²q²) + (-5p²) + (3pq²) + (p²q²)

Remove the brackets,

⇒ 8p²q² - 5p² + 3pq² + p²q²

Rearrange the terms,

⇒ 8p²q² + p²q² - 5p² + 3pq²

Solve the like terms,

⇒ 9p²q² - 5p² + 3pq²

∴ Therefore, the sum of the expressions is 9p²q² - 5p² + 3pq².
