Solution for 5z^2+6z+14=0 equation:


Simplifying
5z2 + 6z + 14 = 0

Reorder the terms:
14 + 6z + 5z2 = 0

Solving
14 + 6z + 5z2 = 0

Solving for variable 'z'.

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

Divide each side by '5'.
2.8 + 1.2z + z2 = 0

Move the constant term to the right:

Add '-2.8' to each side of the equation.
2.8 + 1.2z + -2.8 + z2 = 0 + -2.8

Reorder the terms:
2.8 + -2.8 + 1.2z + z2 = 0 + -2.8

Combine like terms: 2.8 + -2.8 = 0.0
0.0 + 1.2z + z2 = 0 + -2.8
1.2z + z2 = 0 + -2.8

Combine like terms: 0 + -2.8 = -2.8
1.2z + z2 = -2.8

The z term is 1.2z.  Take half its coefficient (0.6).
Square it (0.36) and add it to both sides.

Add '0.36' to each side of the equation.
1.2z + 0.36 + z2 = -2.8 + 0.36

Reorder the terms:
0.36 + 1.2z + z2 = -2.8 + 0.36

Combine like terms: -2.8 + 0.36 = -2.44
0.36 + 1.2z + z2 = -2.44

Factor a perfect square on the left side:
(z + 0.6)(z + 0.6) = -2.44

Can't calculate square root of the right side.

The solution to this equation could not be determined.
