Factor the following:
3 y^2 - 22 y - 16
Factor the quadratic 3 y^2 - 22 y - 16. The coefficient of y^2 is 3 and the constant term is -16. The product of 3 and -16 is -48. The factors of -48 which sum to -22 are 2 and -24. So 3 y^2 - 22 y - 16 = 3 y^2 - 24 y + 2 y - 16 = y (3 y + 2) - 8 (3 y + 2):
y (3 y + 2) - 8 (3 y + 2)
Factor 3 y + 2 from y (3 y + 2) - 8 (3 y + 2):
Answer: | (3 y + 2) (y - 8)
