Question

Factor

Answer 1

(12x+13)2 hope this helps

Answer 2

Answer: D) $(12x+13)^2$

Step-by-step explanation:

The given polynomial : $144x^2 + 312x + 169$

We can write the above expression as :

$(12x)^2+2(12x)(11)+(13)^2$

Using identity $a^2+2ab+b^2=(a+b)^2$,  we have a= 12x , b=11

$\Rightarrow\ (12x)^2+2(12x)(11)+(13)^2=(12x+13)^2$

Hence, factors of the given polynomial will be $(12x+13)^2$.

Thus , the correct answer is option (D).
