Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-0.3' to each side of the equation.
0.3 + -1.7x + -0.3 + x2 = 0 + -0.3

Reorder the terms:
0.3 + -0.3 + -1.7x + x2 = 0 + -0.3

Combine like terms: 0.3 + -0.3 = 0.0
0.0 + -1.7x + x2 = 0 + -0.3
-1.7x + x2 = 0 + -0.3

Combine like terms: 0 + -0.3 = -0.3
-1.7x + x2 = -0.3

The x term is -1.7x.  Take half its coefficient (-0.85).
Square it (0.7225) and add it to both sides.

Add '0.7225' to each side of the equation.
-1.7x + 0.7225 + x2 = -0.3 + 0.7225

Reorder the terms:
0.7225 + -1.7x + x2 = -0.3 + 0.7225

Combine like terms: -0.3 + 0.7225 = 0.4225
0.7225 + -1.7x + x2 = 0.4225

Factor a perfect square on the left side:
(x + -0.85)(x + -0.85) = 0.4225

Calculate the square root of the right side: 0.65

Break this problem into two subproblems by setting 
(x + -0.85) equal to 0.65 and -0.65.

Subproblem 1

x + -0.85 = 0.65 Simplifying x + -0.85 = 0.65 Reorder the terms: -0.85 + x = 0.65 Solving -0.85 + x = 0.65 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.85' to each side of the equation. -0.85 + 0.85 + x = 0.65 + 0.85 Combine like terms: -0.85 + 0.85 = 0.00 0.00 + x = 0.65 + 0.85 x = 0.65 + 0.85 Combine like terms: 0.65 + 0.85 = 1.5 x = 1.5 Simplifying x = 1.5

Subproblem 2

x + -0.85 = -0.65 Simplifying x + -0.85 = -0.65 Reorder the terms: -0.85 + x = -0.65 Solving -0.85 + x = -0.65 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.85' to each side of the equation. -0.85 + 0.85 + x = -0.65 + 0.85 Combine like terms: -0.85 + 0.85 = 0.00 0.00 + x = -0.65 + 0.85 x = -0.65 + 0.85 Combine like terms: -0.65 + 0.85 = 0.2 x = 0.2 Simplifying x = 0.2

Solution

The solution to the problem is based on the solutions from the subproblems. x = {1.5, 0.2}
