Simplifying -1x2 + 970x + -630000 = 0 Reorder the terms: -630000 + 970x + -1x2 = 0 Solving -630000 + 970x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 630000 + -970x + x2 = 0 Move the constant term to the right: Add '-630000' to each side of the equation. 630000 + -970x + -630000 + x2 = 0 + -630000 Reorder the terms: 630000 + -630000 + -970x + x2 = 0 + -630000 Combine like terms: 630000 + -630000 = 0 0 + -970x + x2 = 0 + -630000 -970x + x2 = 0 + -630000 Combine like terms: 0 + -630000 = -630000 -970x + x2 = -630000 The x term is -970x. Take half its coefficient (-485). Square it (235225) and add it to both sides. Add '235225' to each side of the equation. -970x + 235225 + x2 = -630000 + 235225 Reorder the terms: 235225 + -970x + x2 = -630000 + 235225 Combine like terms: -630000 + 235225 = -394775 235225 + -970x + x2 = -394775 Factor a perfect square on the left side: (x + -485)(x + -485) = -394775 Can't calculate square root of the right side. The solution to this equation could not be determined.
