Simplifying 3x2 + x = -5.7 Reorder the terms: x + 3x2 = -5.7 Solving x + 3x2 = -5.7 Solving for variable 'x'. Reorder the terms: 5.7 + x + 3x2 = -5.7 + 5.7 Combine like terms: -5.7 + 5.7 = 0.0 5.7 + x + 3x2 = 0.0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 1.9 + 0.3333333333x + x2 = 0.0 Move the constant term to the right: Add '-1.9' to each side of the equation. 1.9 + 0.3333333333x + -1.9 + x2 = 0.0 + -1.9 Reorder the terms: 1.9 + -1.9 + 0.3333333333x + x2 = 0.0 + -1.9 Combine like terms: 1.9 + -1.9 = 0.0 0.0 + 0.3333333333x + x2 = 0.0 + -1.9 0.3333333333x + x2 = 0.0 + -1.9 Combine like terms: 0.0 + -1.9 = -1.9 0.3333333333x + x2 = -1.9 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.3333333333x + 0.25 + x2 = -1.9 + 0.25 Reorder the terms: 0.25 + 0.3333333333x + x2 = -1.9 + 0.25 Combine like terms: -1.9 + 0.25 = -1.65 0.25 + 0.3333333333x + x2 = -1.65 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -1.65 Can't calculate square root of the right side. The solution to this equation could not be determined.
