Simplifying 7 + 4x + 5x2 = 0 Solving 7 + 4x + 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'. 1.4 + 0.8x + x2 = 0 Move the constant term to the right: Add '-1.4' to each side of the equation. 1.4 + 0.8x + -1.4 + x2 = 0 + -1.4 Reorder the terms: 1.4 + -1.4 + 0.8x + x2 = 0 + -1.4 Combine like terms: 1.4 + -1.4 = 0.0 0.0 + 0.8x + x2 = 0 + -1.4 0.8x + x2 = 0 + -1.4 Combine like terms: 0 + -1.4 = -1.4 0.8x + x2 = -1.4 The x term is 0.8x. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8x + 0.16 + x2 = -1.4 + 0.16 Reorder the terms: 0.16 + 0.8x + x2 = -1.4 + 0.16 Combine like terms: -1.4 + 0.16 = -1.24 0.16 + 0.8x + x2 = -1.24 Factor a perfect square on the left side: (x + 0.4)(x + 0.4) = -1.24 Can't calculate square root of the right side. The solution to this equation could not be determined.
