SOLUTION: factor by grouping: 30y^2 + 10y - 20 30y^2 - 20y + 30y - 20 (30y^2 - 20y) + (30y - 20) 10(y + 1)(3y - 2) not even sure if I laid that out right but this one was tricky

Question 46911: factor by grouping:

30y^2 + 10y - 20
30y^2 - 20y + 30y - 20
(30y^2 - 20y) + (30y - 20)
10(y + 1)(3y - 2)
not even sure if I laid that out right but this one was tricky
