2a^2-3a+6=0

Solution for 2a^2-3a+6=0 equation:

Simplifying
2a2 + -3a + 6 = 0

Reorder the terms:
6 + -3a + 2a2 = 0

Solving
6 + -3a + 2a2 = 0

Solving for variable 'a'.

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

Divide each side by '2'.
3 + -1.5a + a2 = 0

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -1.5a + -3 + a2 = 0 + -3

Reorder the terms:
3 + -3 + -1.5a + a2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1.5a + a2 = 0 + -3
-1.5a + a2 = 0 + -3

Combine like terms: 0 + -3 = -3
-1.5a + a2 = -3

The a term is -1.5a.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5a + 0.5625 + a2 = -3 + 0.5625

Reorder the terms:
0.5625 + -1.5a + a2 = -3 + 0.5625

Combine like terms: -3 + 0.5625 = -2.4375
0.5625 + -1.5a + a2 = -2.4375

Factor a perfect square on the left side:
(a + -0.75)(a + -0.75) = -2.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
