Simplifying x(4x + 5) = -7 Reorder the terms: x(5 + 4x) = -7 (5 * x + 4x * x) = -7 (5x + 4x2) = -7 Solving 5x + 4x2 = -7 Solving for variable 'x'. Reorder the terms: 7 + 5x + 4x2 = -7 + 7 Combine like terms: -7 + 7 = 0 7 + 5x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.75 + 1.25x + x2 = 0 Move the constant term to the right: Add '-1.75' to each side of the equation. 1.75 + 1.25x + -1.75 + x2 = 0 + -1.75 Reorder the terms: 1.75 + -1.75 + 1.25x + x2 = 0 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + 1.25x + x2 = 0 + -1.75 1.25x + x2 = 0 + -1.75 Combine like terms: 0 + -1.75 = -1.75 1.25x + x2 = -1.75 The x term is 1.25x. Take half its coefficient (0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. 1.25x + 0.390625 + x2 = -1.75 + 0.390625 Reorder the terms: 0.390625 + 1.25x + x2 = -1.75 + 0.390625 Combine like terms: -1.75 + 0.390625 = -1.359375 0.390625 + 1.25x + x2 = -1.359375 Factor a perfect square on the left side: (x + 0.625)(x + 0.625) = -1.359375 Can't calculate square root of the right side. The solution to this equation could not be determined.
