Simplifying -1x2 + 7x + -19 = 0 Reorder the terms: -19 + 7x + -1x2 = 0 Solving -19 + 7x + -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'. 19 + -7x + x2 = 0 Move the constant term to the right: Add '-19' to each side of the equation. 19 + -7x + -19 + x2 = 0 + -19 Reorder the terms: 19 + -19 + -7x + x2 = 0 + -19 Combine like terms: 19 + -19 = 0 0 + -7x + x2 = 0 + -19 -7x + x2 = 0 + -19 Combine like terms: 0 + -19 = -19 -7x + x2 = -19 The x term is -7x. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7x + 12.25 + x2 = -19 + 12.25 Reorder the terms: 12.25 + -7x + x2 = -19 + 12.25 Combine like terms: -19 + 12.25 = -6.75 12.25 + -7x + x2 = -6.75 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = -6.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
