Simplifying 5x2 + -7x + 16 = 0 Reorder the terms: 16 + -7x + 5x2 = 0 Solving 16 + -7x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 3.2 + -1.4x + x2 = 0 Move the constant term to the right: Add '-3.2' to each side of the equation. 3.2 + -1.4x + -3.2 + x2 = 0 + -3.2 Reorder the terms: 3.2 + -3.2 + -1.4x + x2 = 0 + -3.2 Combine like terms: 3.2 + -3.2 = 0.0 0.0 + -1.4x + x2 = 0 + -3.2 -1.4x + x2 = 0 + -3.2 Combine like terms: 0 + -3.2 = -3.2 -1.4x + x2 = -3.2 The x term is -1.4x. Take half its coefficient (-0.7). Square it (0.49) and add it to both sides. Add '0.49' to each side of the equation. -1.4x + 0.49 + x2 = -3.2 + 0.49 Reorder the terms: 0.49 + -1.4x + x2 = -3.2 + 0.49 Combine like terms: -3.2 + 0.49 = -2.71 0.49 + -1.4x + x2 = -2.71 Factor a perfect square on the left side: (x + -0.7)(x + -0.7) = -2.71 Can't calculate square root of the right side. The solution to this equation could not be determined.
