Answer:

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

Explanation:

ax² + bx + c can be factored using the AC method:

1. Multiply a and c.

2. Find factors of ac that add up to b.

3. Divide each factor by a; reduce the fractions.

4. The denominator is the coefficient, the numerator is the constant.

6x² + 5x + 1

1. ac = 6 × 1 = 6

2. Factors of 6 that add up to 5: 2 and 3.

3. 2/6 = 1/3, and 3/6 = 1/2

4. The factors are 3x+1 and 2x+1.

6x² + 5x + 1 = (3x + 1) (2x + 1)
