Solve 1+c^2 - ScanMath

Evaluate

1 + c^{2}

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

1 + c^{2} = 0

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

c^{2} = 0 - 1

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

c^{2} = - 1

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

c = \pm - 1

Simplify the expression

c = \pm i

Separate the equation into 2 possible cases

c = i c = - i

Solution

c_{1} = - i, c_{2} = i

Find the roots
