Question

factorise x^2-16y^2
please it's argent ​

Answer 1

Required Answer:-

Given To Factorise:

• x² - 16y²

Solution:

Given that,

= x² - 16y²

This can be written as,

= (x)² - (4y)²

We know that,

→ a² - b² = (a + b)(a - b)

So,

= (x)² - (4y)²

= (x + 4y)(x - 4y)

This can't be factorised more.

→ Hence, the factorised form of the given polynomial is (x + 4y)(x - 4y)

Answer:

• (x + 4y)(x - 4y)

Answer 2

Answer:

x^2-16y^2

Step-by-step explanation:

Referring to the difference of two squares

x² - 16y²

= x² - (4y)²

= (x - 4y) (x + 4y)

(By Using the Identity - a² - b² = (a - b) (a + b)

From this answer, you can see that:

a = x

b = 4y
