s^2-3s+4=0

Solution for s^2-3s+4=0 equation:

Simplifying
s2 + -3s + 4 = 0

Reorder the terms:
4 + -3s + s2 = 0

Solving
4 + -3s + s2 = 0

Solving for variable 's'.

Begin completing the square.

Move the constant term to the right:

Add '-4' to each side of the equation.
4 + -3s + -4 + s2 = 0 + -4

Reorder the terms:
4 + -4 + -3s + s2 = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -3s + s2 = 0 + -4
-3s + s2 = 0 + -4

Combine like terms: 0 + -4 = -4
-3s + s2 = -4

The s term is -3s.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3s + 2.25 + s2 = -4 + 2.25

Reorder the terms:
2.25 + -3s + s2 = -4 + 2.25

Combine like terms: -4 + 2.25 = -1.75
2.25 + -3s + s2 = -1.75

Factor a perfect square on the left side:
(s + -1.5)(s + -1.5) = -1.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
