Simplifying (7x2 + -1x + 2) + (-5x2 + 4x + 3) = 0 Reorder the terms: (2 + -1x + 7x2) + (-5x2 + 4x + 3) = 0 Remove parenthesis around (2 + -1x + 7x2) 2 + -1x + 7x2 + (-5x2 + 4x + 3) = 0 Reorder the terms: 2 + -1x + 7x2 + (3 + 4x + -5x2) = 0 Remove parenthesis around (3 + 4x + -5x2) 2 + -1x + 7x2 + 3 + 4x + -5x2 = 0 Reorder the terms: 2 + 3 + -1x + 4x + 7x2 + -5x2 = 0 Combine like terms: 2 + 3 = 5 5 + -1x + 4x + 7x2 + -5x2 = 0 Combine like terms: -1x + 4x = 3x 5 + 3x + 7x2 + -5x2 = 0 Combine like terms: 7x2 + -5x2 = 2x2 5 + 3x + 2x2 = 0 Solving 5 + 3x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 2.5 + 1.5x + x2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + 1.5x + -2.5 + x2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + 1.5x + x2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + 1.5x + x2 = 0 + -2.5 1.5x + x2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 1.5x + x2 = -2.5 The x term is 1.5x. Take half its coefficient (0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. 1.5x + 0.5625 + x2 = -2.5 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = -2.5 + 0.5625 Combine like terms: -2.5 + 0.5625 = -1.9375 0.5625 + 1.5x + x2 = -1.9375 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = -1.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
