You just have to use trial and error on this one to find the two factors. Use the FOIL method of multiplying to check and see if the factors add up to the original statement.
(4y - 1)(5y + 2)
(4y + 1)(3y + 2)
y(3y^2 - 12y + 4)
(3x + 3y)(x + y) = 3(x + y)2
2(x - 3y + 7z)
(3y + 5)(y - 2)
5(x + 2 + 3y)
3(2 + y)
It is: 2(x+3y) when factored
2(5x + 3y)(2x + 5y)
(3y - 2)(y - 4)
2(y^2 + 3y - 2)
