Answer 2

Step-by-step explanation:

a²—b²=(a+b)(a-b).

That is (a² - b²) we are going to see some example problems based on this formula.

Question 1 :

Expand (5x)² - 3 ²

Solution:

Here the question is in the form of (a²- b²) . Instead of a we have "5x" and instead of b we have "3" . So we need to apply the formula (a + b) (a - b) and we need to apply those values instead of a and b

(5x)² - 3² = (5x + 3) (5x - 3) Ans.
