Simplifying 0 = 0.0002x2 + -0.316x + 127.9 Reorder the terms: 0 = 127.9 + -0.316x + 0.0002x2 Solving 0 = 127.9 + -0.316x + 0.0002x2 Solving for variable 'x'. Combine like terms: 0 + -127.9 = -127.9 -127.9 + 0.316x + -0.0002x2 = 127.9 + -0.316x + 0.0002x2 + -127.9 + 0.316x + -0.0002x2 Reorder the terms: -127.9 + 0.316x + -0.0002x2 = 127.9 + -127.9 + -0.316x + 0.316x + 0.0002x2 + -0.0002x2 Combine like terms: 127.9 + -127.9 = 0.0 -127.9 + 0.316x + -0.0002x2 = 0.0 + -0.316x + 0.316x + 0.0002x2 + -0.0002x2 -127.9 + 0.316x + -0.0002x2 = -0.316x + 0.316x + 0.0002x2 + -0.0002x2 Combine like terms: -0.316x + 0.316x = 0.000 -127.9 + 0.316x + -0.0002x2 = 0.000 + 0.0002x2 + -0.0002x2 -127.9 + 0.316x + -0.0002x2 = 0.0002x2 + -0.0002x2 Combine like terms: 0.0002x2 + -0.0002x2 = 0.0000 -127.9 + 0.316x + -0.0002x2 = 0.0000 Begin completing the square. Divide all terms by -0.0002 the coefficient of the squared term: Divide each side by '-0.0002'. 639500 + -1580x + x2 = 0 Move the constant term to the right: Add '-639500' to each side of the equation. 639500 + -1580x + -639500 + x2 = 0 + -639500 Reorder the terms: 639500 + -639500 + -1580x + x2 = 0 + -639500 Combine like terms: 639500 + -639500 = 0 0 + -1580x + x2 = 0 + -639500 -1580x + x2 = 0 + -639500 Combine like terms: 0 + -639500 = -639500 -1580x + x2 = -639500 The x term is -1580x. Take half its coefficient (-790). Square it (624100) and add it to both sides. Add '624100' to each side of the equation. -1580x + 624100 + x2 = -639500 + 624100 Reorder the terms: 624100 + -1580x + x2 = -639500 + 624100 Combine like terms: -639500 + 624100 = -15400 624100 + -1580x + x2 = -15400 Factor a perfect square on the left side: (x + -790)(x + -790) = -15400 Can't calculate square root of the right side. The solution to this equation could not be determined.
