2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
It is 4xy.
4xy + x3y + yx2 + yx + 3yx = x3y + x2y + 8xy = (xy)(x2y + x + 8)
4xy - 2y(x + 4) = 4xy - 2xy - 8y = 2xy - 8y = 2y(x - 4)
(x + 3)(x + 4y)
2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
It is 4xy.
It is 4xy.
4xy + x3y + yx2 + yx + 3yx = x3y + x2y + 8xy = (xy)(x2y + x + 8)
It is 4xy.
4xy - 2y(x + 4) = 4xy - 2xy - 8y = 2xy - 8y = 2y(x - 4)
(x + 3)(x + 4y)
If by "What is the answer to", you mean "How do you factor", then we can solve it as follows: x2 + 13xy + 36y2 = x2 + 4xy + 9xy + 36y2 = x(x + 4y) + 9y(x + 4y) = (x + 9y)(x + 4y)
the difference between 2x2 +4xy-3 and x2-2xy-4 is?
It is 4xy.
