Solution for 20x^2-14x+3=0 equation:


Simplifying
20x2 + -14x + 3 = 0

Reorder the terms:
3 + -14x + 20x2 = 0

Solving
3 + -14x + 20x2 = 0

Solving for variable 'x'.

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

Divide each side by '20'.
0.15 + -0.7x + x2 = 0

Move the constant term to the right:

Add '-0.15' to each side of the equation.
0.15 + -0.7x + -0.15 + x2 = 0 + -0.15

Reorder the terms:
0.15 + -0.15 + -0.7x + x2 = 0 + -0.15

Combine like terms: 0.15 + -0.15 = 0.00
0.00 + -0.7x + x2 = 0 + -0.15
-0.7x + x2 = 0 + -0.15

Combine like terms: 0 + -0.15 = -0.15
-0.7x + x2 = -0.15

The x term is -0.7x.  Take half its coefficient (-0.35).
Square it (0.1225) and add it to both sides.

Add '0.1225' to each side of the equation.
-0.7x + 0.1225 + x2 = -0.15 + 0.1225

Reorder the terms:
0.1225 + -0.7x + x2 = -0.15 + 0.1225

Combine like terms: -0.15 + 0.1225 = -0.0275
0.1225 + -0.7x + x2 = -0.0275

Factor a perfect square on the left side:
(x + -0.35)(x + -0.35) = -0.0275

Can't calculate square root of the right side.

The solution to this equation could not be determined.
