Simplifying 10x2 + -2.88x + 2.07 = 0 Reorder the terms: 2.07 + -2.88x + 10x2 = 0 Solving 2.07 + -2.88x + 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'. 0.207 + -0.288x + x2 = 0 Move the constant term to the right: Add '-0.207' to each side of the equation. 0.207 + -0.288x + -0.207 + x2 = 0 + -0.207 Reorder the terms: 0.207 + -0.207 + -0.288x + x2 = 0 + -0.207 Combine like terms: 0.207 + -0.207 = 0.000 0.000 + -0.288x + x2 = 0 + -0.207 -0.288x + x2 = 0 + -0.207 Combine like terms: 0 + -0.207 = -0.207 -0.288x + x2 = -0.207 The x term is -0.288x. Take half its coefficient (-0.144). Square it (0.020736) and add it to both sides. Add '0.020736' to each side of the equation. -0.288x + 0.020736 + x2 = -0.207 + 0.020736 Reorder the terms: 0.020736 + -0.288x + x2 = -0.207 + 0.020736 Combine like terms: -0.207 + 0.020736 = -0.186264 0.020736 + -0.288x + x2 = -0.186264 Factor a perfect square on the left side: (x + -0.144)(x + -0.144) = -0.186264 Can't calculate square root of the right side. The solution to this equation could not be determined.
