Simplifying 5x2 + 6x + 15 = 0 Reorder the terms: 15 + 6x + 5x2 = 0 Solving 15 + 6x + 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'. 3 + 1.2x + x2 = 0 Move the constant term to the right: Add '-3' to each side of the equation. 3 + 1.2x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + 1.2x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 1.2x + x2 = 0 + -3 1.2x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 1.2x + x2 = -3 The x term is 1.2x. Take half its coefficient (0.6). Square it (0.36) and add it to both sides. Add '0.36' to each side of the equation. 1.2x + 0.36 + x2 = -3 + 0.36 Reorder the terms: 0.36 + 1.2x + x2 = -3 + 0.36 Combine like terms: -3 + 0.36 = -2.64 0.36 + 1.2x + x2 = -2.64 Factor a perfect square on the left side: (x + 0.6)(x + 0.6) = -2.64 Can't calculate square root of the right side. The solution to this equation could not be determined.
