solvefor x,x(n)=(1/2)^nu+2^nu(-n-1)

Solution

solve for

x, x (n) = (\frac{1}{2})^{n} u + 2^{n} u (- n - 1)

Solution

x = \frac{- n u \cdot 4 ^{n} - u \cdot 4 ^{n} + u \cdot 1 ^{n}}{2 ^{n} n}; n \neq = 0

Solution steps

x (n) = (\frac{1}{2})^{n} u + 2^{n} u (- n - 1)

Divide both sides by

n; n \neq = 0

x = \frac{( \frac{1}{2} ) ^{n} u + 2 ^{n} u ( - n - 1 )}{n}; n \neq = 0

Simplify

\frac{( \frac{1}{2} ) ^{n} u + 2 ^{n} u ( - n - 1 )}{n} : \frac{- n u \cdot 4 ^{n} - u \cdot 4 ^{n} + u \cdot 1 ^{n}}{2 ^{n} n}

x = \frac{- n u \cdot 4 ^{n} - u \cdot 4 ^{n} + u \cdot 1 ^{n}}{2 ^{n} n}; n \neq = 0
