(5y + 3)(y - 1)
You can get this because you know that the only factors of 5 are 5 and 1, so you start
(5y )(y )
Then, to multiply two things to get -3, it has to be -3 and 1, or -1 and 3. Guessing and checking works from here, or you can think it out. 5 x -1 would give you -5, and 3 x 1 is 3, so this combination would give you the -2 coefficient needed to get the answer. FOIL to check.
(5y + 3)(y - 1)
(3 - 2y)(3 + 2y)
7
2y(2y - 1)(2y - 3)
2y(2y - 1)(2y - 3)
-5y2+3x+2y
Example: factor 2y+6Both 2y and 6 have a common factor of 2:2y is 2 × y6 is 2 × 3So you can factor the whole expression into:2y+6 = 2(y+3)So, 2y+6 has been "factored into" 2 and y+3
The GCF is 5y.20y3 = (5y)(4y2)5y2 = (5y)(y)45y = (5y)(9)
Without an equality sign it is not an equation but the expression can be factored as (2y-3)(2y+3)
(y - 3)(2y + 1)
2x^2y^2(3x^2y^3 - 2xy + 1)
3(x + 2y)
