Simplifying 10x2 + 18x + 39 = 0 Reorder the terms: 39 + 18x + 10x2 = 0 Solving 39 + 18x + 10x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 3.9 + 1.8x + x2 = 0 Move the constant term to the right: Add '-3.9' to each side of the equation. 3.9 + 1.8x + -3.9 + x2 = 0 + -3.9 Reorder the terms: 3.9 + -3.9 + 1.8x + x2 = 0 + -3.9 Combine like terms: 3.9 + -3.9 = 0.0 0.0 + 1.8x + x2 = 0 + -3.9 1.8x + x2 = 0 + -3.9 Combine like terms: 0 + -3.9 = -3.9 1.8x + x2 = -3.9 The x term is 1.8x. Take half its coefficient (0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. 1.8x + 0.81 + x2 = -3.9 + 0.81 Reorder the terms: 0.81 + 1.8x + x2 = -3.9 + 0.81 Combine like terms: -3.9 + 0.81 = -3.09 0.81 + 1.8x + x2 = -3.09 Factor a perfect square on the left side: (x + 0.9)(x + 0.9) = -3.09 Can't calculate square root of the right side. The solution to this equation could not be determined.
