Question

Factor by grouping.. . 3x^2 + 7x – 6. A. (3x – 2)(x – 3) . B. (3x – 2)(x + 3) . C. (x + 3)(3x + 2) . D. (3x + 2)(x – 3)

Answer 1

The correct answer is letter "B. (3x – 2)(x + 3)."

This is how to factor the given polynomial:
3x^2 + 7x – 6
(3x - 2) (x + 3) 

It takes trial and error in order to get the final factor of a given polynomial. It has to be exact and correctly done.
