`(dy)/dx=5-8x`
This differential equation is separable since it has a form
`N(y) (dy)/dx=M(x)`
And, it can be re-written as
`N(y) dy = M(x) dx`
So separating the variables, the equation becomes
`dy=(5-8x)dx`
Integrating both sides, it result to
`int dy = int (5-8x)dx`
`y + C_1 = 5x - (8x^2)/2 + C_2`
`y+ C_1 = 5x - 4x^2 + C_2`
Isolating the y, it becomes
`y = 5x - 4x^2 + C_2 -C_1`
Since C2 and C1 are constants, it can be expressed as a single constant C.
`y=5x-4x^2+C`
`y=-4x^2 + 5x + C`
Therefore, the general solution of the given differential equation is `y=-4x^2 + 5x + C` .
