Simplifying -4.9x2 + 3.43x + -58.8 = 0 Reorder the terms: -58.8 + 3.43x + -4.9x2 = 0 Solving -58.8 + 3.43x + -4.9x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -4.9 the coefficient of the squared term: Divide each side by '-4.9'. 12 + -0.7x + x2 = 0 Move the constant term to the right: Add '-12' to each side of the equation. 12 + -0.7x + -12 + x2 = 0 + -12 Reorder the terms: 12 + -12 + -0.7x + x2 = 0 + -12 Combine like terms: 12 + -12 = 0 0 + -0.7x + x2 = 0 + -12 -0.7x + x2 = 0 + -12 Combine like terms: 0 + -12 = -12 -0.7x + x2 = -12 The x term is -0.7x. Take half its coefficient (-0.35). Square it (0.1225) and add it to both sides. Add '0.1225' to each side of the equation. -0.7x + 0.1225 + x2 = -12 + 0.1225 Reorder the terms: 0.1225 + -0.7x + x2 = -12 + 0.1225 Combine like terms: -12 + 0.1225 = -11.8775 0.1225 + -0.7x + x2 = -11.8775 Factor a perfect square on the left side: (x + -0.35)(x + -0.35) = -11.8775 Can't calculate square root of the right side. The solution to this equation could not be determined.
