Question

factorise 16m2

– 121​

Answer 1

Answer:

16m² - 121 = (4m + 11)(4m - 11)

Step-by-step explanation:

Here we will use the identity:

a² - b² = (a + b)(a - b)

In this question, we will take a² as 16m², and b² as 121

Therefore, a = 4m, b = 11

16m² - 121 = (4m + 11)(4m - 11)

Hence solved
