x = 8 and y = 0
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) .
The equation is -2y + 16 = 10
4xy - 2y(x + 4) = 4xy - 2xy - 8y = 2xy - 8y = 2y(x - 4)
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) = (x - 1)(4x + 2y) = 2(x - 1)(2x + y)
2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
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) .
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) (4x + 2y)(x - 1).
That equals 2xy + 3y which factors to y(2x + 3)
The equation is -2y + 16 = 10
4xy - 2y(x + 4) = 4xy - 2xy - 8y = 2xy - 8y = 2y(x - 4)
4x2 - 4x + 2xy - 2y = 4x(x - 1) + 2y(x - 1) = (x - 1)(4x + 2y) = 2(x - 1)(2x + y)
L = 3x + 2y
2y + 2xy' + 4y + 4xy' = 0 6y + 6xy' = 0 y' = -y/x
-2x - 2y = -122x + 2y = 122y = 12 - 2xy = 6 - x
2y+3y-7y+4=16 -2y=12y=-6Check it-12-18+42+4=16-30+46=1616=16
(2x + 2y) is exactly the same thing as 2(x+y). In order to know how much it actually is, you have to know the numerical values of both 'x' and 'y'.
