1. Verify that the given differential equation is not exact.
(x^2 + 2xy − y^2) dx + (y^2 + 2xy − x^2) dy = 0
2. If the given DE is written in the form M(x, y) dx + N(x, y) dy = 0, one has:
My =
Nx = .
Since My and Nx equal, the equation is not exact.
3. Multiply the given differential equation by the integrating factor μ(x, y) = (x + y)^−2 and verify that the new equation is exact.
4. If the new DE is written in the form M(x, y) dx + N(x, y) dy = 0, one has:
My =
Nx = =
Since My and Nx equal, the equation is exact.

answer

false

explanation

these practices describe the manner the land use outcome is attained. land management methods implemented by corporations are a mandatory because they are a driver for better land use results economically, socially and environmentally. corporations are required to understand the connection between land use , and land management practices to support sustainable land use policies

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
