Simplifying -5x2 + 4x + -4 = 0 Reorder the terms: -4 + 4x + -5x2 = 0 Solving -4 + 4x + -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 + -0.8x + x2 = 0 Move the constant term to the right: Add '-0.8' to each side of the equation. 0.8 + -0.8x + -0.8 + x2 = 0 + -0.8 Reorder the terms: 0.8 + -0.8 + -0.8x + x2 = 0 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + -0.8x + x2 = 0 + -0.8 -0.8x + x2 = 0 + -0.8 Combine like terms: 0 + -0.8 = -0.8 -0.8x + x2 = -0.8 The x term is -0.8x. Take half its coefficient (-0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. -0.8x + 0.16 + x2 = -0.8 + 0.16 Reorder the terms: 0.16 + -0.8x + x2 = -0.8 + 0.16 Combine like terms: -0.8 + 0.16 = -0.64 0.16 + -0.8x + x2 = -0.64 Factor a perfect square on the left side: (x + -0.4)(x + -0.4) = -0.64 Can't calculate square root of the right side. The solution to this equation could not be determined.
