Question

factorise 3x² - 27 by using a²-b² = (a+b)(a-b)​

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

Given

3x^2 - 27

Solution

According to the Identity

(a - b)^2

(a^2 + 2ab + b^2)

= (3x^2 - 2 x (3x) x (3x) + 3^2)

= (9x^2 - 18x^2 + 9)

9x^2 - 18x^2 + 9 will be the Answer
