Question

HeLp PlEasE What is the factored form of the following expression? 9x2 + 18x + 9 A. 3(x + 3)(3x + 1) B. 9(x + 1)2 C. (9x + 1)(x + 9) D. 3(x + 1)2 help DDDDDDD:

Answer 1

The answer is option B

Explanation:

9x² + 18x + 9

Factor out 9 from the expression

That's

9( x² + 2x + 1)

Using the identity

a² + 2ab + b² = ( a + b)² factor the expression

We have the final answer as

9( x + 1)²

Hope this helps you
