First, you will need to factor: 10x² + 11x - 6
Because the last term (-6) is a negative, the parentheses will include one plus sign and one minus sign.
Find the factors of 10; they will be either 10 and 1 or 5 and 2.
Find the factors of 6; they will be either 6 and 1 or 3 and 2.
So, the possibilities are:
(10x + 6)(1x - 1) (10x - 6)(1x + 1) (10x + 1)(1x - 6) (10x - 1)(1x + 6)
(5x + 6)(2x - 1) (5x - 6)(2x + 1) (5x + 3)(2x - 2) (5x - 3)(2x + 2)
(5x + 2)(2x - 3) (5x - 2)(2x + 3)
Check each one! The middle term must become +11x.
Once you have determined which one is correct, set each factor equal to zero to find the two answers.
