d(x)=x+8

Solution

d (x) = x + 8

Solution

x = \frac{8}{d - 1}; d \neq = 1

Solution steps

d (x) = x + 8

Expand

d (x) : d x

d x = x + 8

Move

x

to the left side

d x - x = 8

Factor

d x - x : x (d - 1)

x (d - 1) = 8

Divide both sides by

d - 1; d \neq = 1

x = \frac{8}{d - 1}; d \neq = 1

y^{^{''}} + 4 y^{^{'}} + 4 y = 3 sin (t) + 2 e^{2 t}

y^{''}+2y^'-3y=12e^x-6

y^{^{''}} + 2 y^{^{'}} - 3 y = 12 e^{x} - 6

(D+1)^2y=x^2e^{-x}

(D + 1)^{2} y = x^{2} e^{- x}

y^{''}+4y^'+4y=(x+5)e^{-2x}

y^{^{''}} + 4 y^{^{'}} + 4 y = (x + 5) e^{- 2 x}
