Simplifying 5x(x + 2) + -3(x + -1) = 0 Reorder the terms: 5x(2 + x) + -3(x + -1) = 0 (2 * 5x + x * 5x) + -3(x + -1) = 0 (10x + 5x2) + -3(x + -1) = 0 Reorder the terms: 10x + 5x2 + -3(-1 + x) = 0 10x + 5x2 + (-1 * -3 + x * -3) = 0 10x + 5x2 + (3 + -3x) = 0 Reorder the terms: 3 + 10x + -3x + 5x2 = 0 Combine like terms: 10x + -3x = 7x 3 + 7x + 5x2 = 0 Solving 3 + 7x + 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'. 0.6 + 1.4x + x2 = 0 Move the constant term to the right: Add '-0.6' to each side of the equation. 0.6 + 1.4x + -0.6 + x2 = 0 + -0.6 Reorder the terms: 0.6 + -0.6 + 1.4x + x2 = 0 + -0.6 Combine like terms: 0.6 + -0.6 = 0.0 0.0 + 1.4x + x2 = 0 + -0.6 1.4x + x2 = 0 + -0.6 Combine like terms: 0 + -0.6 = -0.6 1.4x + x2 = -0.6 The x term is 1.4x. Take half its coefficient (0.7). Square it (0.49) and add it to both sides. Add '0.49' to each side of the equation. 1.4x + 0.49 + x2 = -0.6 + 0.49 Reorder the terms: 0.49 + 1.4x + x2 = -0.6 + 0.49 Combine like terms: -0.6 + 0.49 = -0.11 0.49 + 1.4x + x2 = -0.11 Factor a perfect square on the left side: (x + 0.7)(x + 0.7) = -0.11 Can't calculate square root of the right side. The solution to this equation could not be determined.
