Solve n^2-3-5 - ScanMath

Evaluate

n^{2} - 3 - 5

To find the roots of the expression,set the expression equal to 0

n^{2} - 3 - 5 = 0

Subtract the numbers

n^{2} - 8 = 0

Move the constant to the right-hand side and change its sign

n^{2} = 0 + 8

Removing 0 doesn't change the value,so remove it from the expression

n^{2} = 8

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

n = \pm 8

Simplify the expression

More Steps

n = \pm 22

Separate the equation into 2 possible cases

n = 22 n = - 22

Solution

n_{1} = - 22, n_{2} = 22

Alternative Form

n_{1} \approx - 2.828427, n_{2} \approx 2.828427
