Factor 15x3

5x2 + 6x 2 by grouping. What is the resulting expression?

(5x2 + 2) (3x 1)

(5x2 2) (3x + 1)

(15x2 + 2) (x 1)

(15x2)

In a simpler form the awnser is A (5x^2 + 2) (3x-1)

To factor 15x³ - 5x² + 6x - 2 by grouping, we need to find common factors and group them, so we have 15x³ - 5x² + 6x - 2 (15x³ - 5x²) + (6x - 2) 5x² (3x - 1) + 2 (3x - 1) Factoring out the common factor, we have (3x - 1) (5x² + 2). Thus, the answer is A: (5x² + 2) (3x - 1).
