Simplifying 4 + -3x + 5x2 = 0 Solving 4 + -3x + 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 + -0.6x + x2 = 0 Move the constant term to the right: Add '-0.8' to each side of the equation. 0.8 + -0.6x + -0.8 + x2 = 0 + -0.8 Reorder the terms: 0.8 + -0.8 + -0.6x + x2 = 0 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + -0.6x + x2 = 0 + -0.8 -0.6x + x2 = 0 + -0.8 Combine like terms: 0 + -0.8 = -0.8 -0.6x + x2 = -0.8 The x term is -0.6x. Take half its coefficient (-0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. -0.6x + 0.09 + x2 = -0.8 + 0.09 Reorder the terms: 0.09 + -0.6x + x2 = -0.8 + 0.09 Combine like terms: -0.8 + 0.09 = -0.71 0.09 + -0.6x + x2 = -0.71 Factor a perfect square on the left side: (x + -0.3)(x + -0.3) = -0.71 Can't calculate square root of the right side. The solution to this equation could not be determined.
