Question

( 36c^2 - (5a + b)^2
​

Answer 1

Answer:

(6c + 5a + b)(6c – 5a – b)

Step-by-step explanation:

Given,

36c2 – (5a + b)2

= (6c)2 – (5a + b)2

By using the formula a2 – b2 = (a + b)(a – b)

We get,

36c2 – (5a + b)2 = (6c)2 – (5a + b)2

= {(6c) + (5a + b)}{(6c) – (5a + b)}

= (6c + 5a + b)(6c – 5a – b)
