2 (2x2 + 2x + xy + y )
it's 2 (2x + y)(x + 1) if you're doing A+
9y cubed plus 2y squared
8-x2y 8-2xy 2xy-8
That equals 2xy + 3y which factors to y(2x + 3)
2y squared * y cubed= 2y^5 (2y to the fifth power)
a(2y - 1)(y + 3)
2(x - 1)(2x + y)
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) (4x + 2y)(x - 1).
2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .
2y + 1
2y^2+5y+2=(2y+1)(y+2)
(2y - 5)(y - 2)
6xyz(3x + 2y + z)
The expression (2x + 2y) does not equal (2xy) or (4xy). Instead, it represents the sum of two terms, (2x) and (2y). If you factor it, you could write it as (2(x + y)), but it does not simplify to a product of (xy).
4xy - 2y(x + 4) = 4xy - 2xy - 8y = 2xy - 8y = 2y(x - 4)
2x^2y^2(3x^2y^3 - 2xy + 1)
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) = (x - 1)(4x + 2y) = 2(x - 1)(2x + y)
If that's -18y2, the answer is (3x - 2y)(x + 9y)
