I WILL MARK BRAINILIEST !!! Factor the polynomial 20x3 + 34x2 + 6x completely.

2x(2x + 3)(5x + 1)
2x(2x + 1)(5x + 3)
2(2x + 3)(5x + 1)
(4x2 + 6x)(5x + 1)

Solution:


\text G\text i\text v\text e\text n\ \text e\text x\text p\text r\text e\text s\text s\text i\text o\text n: 20x^(3) + 34x^(2) + 6x

Step-1: Find the GCF of the terms.


20x^(3) \ \ \ = \ \ \ 2 * 2 * 5 * x * x * x \\34x^(2) \ \ \ = \ \ \ 2 * 17 * x * x \\ 6x \ \ \ \ \ \ = \ \ \ 2 * 3 * x

GCF = 2x

Step-2: Factor the expression using the GCF.


20x^(3) + 34x^(2) + 6x \\\\ {2x(10x^(2) + 17x + 3)}

Step-3: Further factorize.


{2x(10x^(2) + 17x + 3)}


2x(2x + 3)(5x + 1)

Thus, the factorized expression is
2x(2x + 3)(5x + 1).
