Simplifying 0.35x + -1x2 = 670 Solving 0.35x + -1x2 = 670 Solving for variable 'x'. Reorder the terms: -670 + 0.35x + -1x2 = 670 + -670 Combine like terms: 670 + -670 = 0 -670 + 0.35x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 670 + -0.35x + x2 = 0 Move the constant term to the right: Add '-670' to each side of the equation. 670 + -0.35x + -670 + x2 = 0 + -670 Reorder the terms: 670 + -670 + -0.35x + x2 = 0 + -670 Combine like terms: 670 + -670 = 0 0 + -0.35x + x2 = 0 + -670 -0.35x + x2 = 0 + -670 Combine like terms: 0 + -670 = -670 -0.35x + x2 = -670 The x term is -0.35x. Take half its coefficient (-0.175). Square it (0.030625) and add it to both sides. Add '0.030625' to each side of the equation. -0.35x + 0.030625 + x2 = -670 + 0.030625 Reorder the terms: 0.030625 + -0.35x + x2 = -670 + 0.030625 Combine like terms: -670 + 0.030625 = -669.969375 0.030625 + -0.35x + x2 = -669.969375 Factor a perfect square on the left side: (x + -0.175)(x + -0.175) = -669.969375 Can't calculate square root of the right side. The solution to this equation could not be determined.
