-s^2+4s-6=0

Solution for -s^2+4s-6=0 equation:

Simplifying
-1s2 + 4s + -6 = 0

Reorder the terms:
-6 + 4s + -1s2 = 0

Solving
-6 + 4s + -1s2 = 0

Solving for variable 's'.

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
6 + -4s + s2 = 0

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + -4s + -6 + s2 = 0 + -6

Reorder the terms:
6 + -6 + -4s + s2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -4s + s2 = 0 + -6
-4s + s2 = 0 + -6

Combine like terms: 0 + -6 = -6
-4s + s2 = -6

The s term is -4s.  Take half its coefficient (-2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
-4s + 4 + s2 = -6 + 4

Reorder the terms:
4 + -4s + s2 = -6 + 4

Combine like terms: -6 + 4 = -2
4 + -4s + s2 = -2

Factor a perfect square on the left side:
(s + -2)(s + -2) = -2

Can't calculate square root of the right side.
