Question

ii. 49y2 + 84yz + 36z2
Factorice expression​

Answer 1

Step-by-step explanation:

49y^2+84yz+36z^2

(7y+6z)^2

(7y+6z)(7y+6z)

Answer 2

⭐⭐ Hey mate ⭐⭐

Here is the answer :-

We know about the identity ,

(a + b)² = a² + b² + 2ab .

Now ,

We can also say that ,

a² + b² + 2ab = (a + b)² = (a + b)(a + b)

Here ,

given expression = 49y² + 84yz + 36z²

The square root of 49y² is (7y²) and that of 36z² is (6z)² . So,

=> (7y)² + 84yz + (6z)²

=> (7y + 6z)² {as the answer of 2ab here is 84yz}

=> (7y + 6z)(7y + 6z)

$\boxed {Answer\;=\;(7y\;+6z)(7y\;+\;6z)}$

Hope it will be helpful....
