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

Divide each side by '0.05'.
1200 + -70x + x2 = 0

Move the constant term to the right:

Add '-1200' to each side of the equation.
1200 + -70x + -1200 + x2 = 0 + -1200

Reorder the terms:
1200 + -1200 + -70x + x2 = 0 + -1200

Combine like terms: 1200 + -1200 = 0
0 + -70x + x2 = 0 + -1200
-70x + x2 = 0 + -1200

Combine like terms: 0 + -1200 = -1200
-70x + x2 = -1200

The x term is -70x.  Take half its coefficient (-35).
Square it (1225) and add it to both sides.

Add '1225' to each side of the equation.
-70x + 1225 + x2 = -1200 + 1225

Reorder the terms:
1225 + -70x + x2 = -1200 + 1225

Combine like terms: -1200 + 1225 = 25
1225 + -70x + x2 = 25

Factor a perfect square on the left side:
(x + -35)(x + -35) = 25

Calculate the square root of the right side: 5

Break this problem into two subproblems by setting 
(x + -35) equal to 5 and -5.

Subproblem 1

x + -35 = 5 Simplifying x + -35 = 5 Reorder the terms: -35 + x = 5 Solving -35 + x = 5 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '35' to each side of the equation. -35 + 35 + x = 5 + 35 Combine like terms: -35 + 35 = 0 0 + x = 5 + 35 x = 5 + 35 Combine like terms: 5 + 35 = 40 x = 40 Simplifying x = 40

Subproblem 2

x + -35 = -5 Simplifying x + -35 = -5 Reorder the terms: -35 + x = -5 Solving -35 + x = -5 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '35' to each side of the equation. -35 + 35 + x = -5 + 35 Combine like terms: -35 + 35 = 0 0 + x = -5 + 35 x = -5 + 35 Combine like terms: -5 + 35 = 30 x = 30 Simplifying x = 30

Solution

The solution to the problem is based on the solutions from the subproblems. x = {40, 30}
