Simplifying -5x2 + 6x + -4 = 0 Reorder the terms: -4 + 6x + -5x2 = 0 Solving -4 + 6x + -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'. 0.8 + -1.2x + x2 = 0 Move the constant term to the right: Add '-0.8' to each side of the equation. 0.8 + -1.2x + -0.8 + x2 = 0 + -0.8 Reorder the terms: 0.8 + -0.8 + -1.2x + x2 = 0 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + -1.2x + x2 = 0 + -0.8 -1.2x + x2 = 0 + -0.8 Combine like terms: 0 + -0.8 = -0.8 -1.2x + x2 = -0.8 The x term is -1.2x. Take half its coefficient (-0.6). Square it (0.36) and add it to both sides. Add '0.36' to each side of the equation. -1.2x + 0.36 + x2 = -0.8 + 0.36 Reorder the terms: 0.36 + -1.2x + x2 = -0.8 + 0.36 Combine like terms: -0.8 + 0.36 = -0.44 0.36 + -1.2x + x2 = -0.44 Factor a perfect square on the left side: (x + -0.6)(x + -0.6) = -0.44 Can't calculate square root of the right side. The solution to this equation could not be determined.
