Simplifying 5x2 + 7x + 70 = 0 Reorder the terms: 70 + 7x + 5x2 = 0 Solving 70 + 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'. 14 + 1.4x + x2 = 0 Move the constant term to the right: Add '-14' to each side of the equation. 14 + 1.4x + -14 + x2 = 0 + -14 Reorder the terms: 14 + -14 + 1.4x + x2 = 0 + -14 Combine like terms: 14 + -14 = 0 0 + 1.4x + x2 = 0 + -14 1.4x + x2 = 0 + -14 Combine like terms: 0 + -14 = -14 1.4x + x2 = -14 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 = -14 + 0.49 Reorder the terms: 0.49 + 1.4x + x2 = -14 + 0.49 Combine like terms: -14 + 0.49 = -13.51 0.49 + 1.4x + x2 = -13.51 Factor a perfect square on the left side: (x + 0.7)(x + 0.7) = -13.51 Can't calculate square root of the right side. The solution to this equation could not be determined.
