4xy - 2y(x + 4) = 4xy - 2xy - 8y = 2xy - 8y = 2y(x - 4)
2xy
4xy - 2xy
(2x2+4xy-3)-(x2-2xy-4)Answer: x2+6x+1
2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
The greatest common factor of 4xy and -6xy is 2xy. To find the greatest common factor, we first factor out the numbers 4 and -6 to get 2(2xy) and -2(3xy). The greatest common factor is the highest common factor that divides both terms evenly, which in this case is 2xy.
2xy
4xy - 2y(x + 4) = 4xy - 2xy - 8y = 2xy - 8y = 2y(x - 4)
2xy
the difference between 2x2 +4xy-3 and x2-2xy-4 is?
4xy - 2xy
2xy

(2x2+4xy-3)-(x2-2xy-4)Answer: x2+6x+1
2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
(x^2 + 2y)(x^3 - 2xy + y^3) = x^2(x^3 - 2xy + y^3) + 2y(x^3 - 2xy + y^3) Now, let's distribute each term: = x^2 * x^3 - x^2 * 2xy + x^2 * y^3 + 2y * x^3 - 2y * 2xy + 2y * y^3 Now, simplify each term: = x^5 - 2x^3y + x^2y^3 + 2x^3y - 4xy^2 + 2y^4 Now, combine like terms: = x^5 + x^2y^3 - 4xy^2 + 2y^4 So, the expanded form of (x^2 + 2y)(x^3 - 2xy + y^3) is x^5 + x^2y^3 - 4xy^2 + 2y^4.
3x2y - 4xy + 4x
