Solve x^2 [n]=u[n 1]-u[n-2]

Evaluate

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

Remove the parentheses

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

Simplify

More Steps

x^{2} n = 2 u

Rewrite the expression

n x^{2} = 2 u

Divide both sides

\frac{n x ^{2}}{n} = \frac{2 u}{n}

Divide the numbers

x^{2} = \frac{2 u}{n}

Take the root of both sides of the equation and remember to use both positive and negative roots

x = \pm \frac{2 u}{n}

Simplify the expression

More Steps

x = \pm \frac{2 u n}{∣ n ∣}

Solution

x = \frac{2 u n}{∣ n ∣} x = - \frac{2 u n}{∣ n ∣}
