Answer 1

Answer:

(2x + 7) (2x + 7)

Step-by-step explanation:

Given :

To factorize :

$4x^2 + 28x + 49$

Solution :

⇒ $4x^2 + 28x + 49$

By splitting the middle term,

We get,

⇒ $4x^2 + 14x + 14x + 49$

⇒ $2x (2x + 7)+ 7(2x + 7)$

⇒ $(2x + 7) (2x + 7)$

Done,....

Answer 2

Hey ✌

Here is the answer

Product= 4×49=196

Sum=28

$= 4 {x}^{2} + 14x + 14x + 49$

$= 2x(2x + 7) + 7(2x + 7)$

$= (2x + 7)(2x + 7)$
