Simplifying (3x2 + 5x + 2) + -1(4 + -2x) + (5x2 + 7) = 0 Reorder the terms: (2 + 5x + 3x2) + -1(4 + -2x) + (5x2 + 7) = 0 Remove parenthesis around (2 + 5x + 3x2) 2 + 5x + 3x2 + -1(4 + -2x) + (5x2 + 7) = 0 2 + 5x + 3x2 + (4 * -1 + -2x * -1) + (5x2 + 7) = 0 2 + 5x + 3x2 + (-4 + 2x) + (5x2 + 7) = 0 Reorder the terms: 2 + 5x + 3x2 + -4 + 2x + (7 + 5x2) = 0 Remove parenthesis around (7 + 5x2) 2 + 5x + 3x2 + -4 + 2x + 7 + 5x2 = 0 Reorder the terms: 2 + -4 + 7 + 5x + 2x + 3x2 + 5x2 = 0 Combine like terms: 2 + -4 = -2 -2 + 7 + 5x + 2x + 3x2 + 5x2 = 0 Combine like terms: -2 + 7 = 5 5 + 5x + 2x + 3x2 + 5x2 = 0 Combine like terms: 5x + 2x = 7x 5 + 7x + 3x2 + 5x2 = 0 Combine like terms: 3x2 + 5x2 = 8x2 5 + 7x + 8x2 = 0 Solving 5 + 7x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.625 + 0.875x + x2 = 0 Move the constant term to the right: Add '-0.625' to each side of the equation. 0.625 + 0.875x + -0.625 + x2 = 0 + -0.625 Reorder the terms: 0.625 + -0.625 + 0.875x + x2 = 0 + -0.625 Combine like terms: 0.625 + -0.625 = 0.000 0.000 + 0.875x + x2 = 0 + -0.625 0.875x + x2 = 0 + -0.625 Combine like terms: 0 + -0.625 = -0.625 0.875x + x2 = -0.625 The x term is 0.875x. Take half its coefficient (0.4375). Square it (0.19140625) and add it to both sides. Add '0.19140625' to each side of the equation. 0.875x + 0.19140625 + x2 = -0.625 + 0.19140625 Reorder the terms: 0.19140625 + 0.875x + x2 = -0.625 + 0.19140625 Combine like terms: -0.625 + 0.19140625 = -0.43359375 0.19140625 + 0.875x + x2 = -0.43359375 Factor a perfect square on the left side: (x + 0.4375)(x + 0.4375) = -0.43359375 Can't calculate square root of the right side. The solution to this equation could not be determined.
