Simplifying 8x2 + -12x + 29 = 3x + -2 Reorder the terms: 29 + -12x + 8x2 = 3x + -2 Reorder the terms: 29 + -12x + 8x2 = -2 + 3x Solving 29 + -12x + 8x2 = -2 + 3x Solving for variable 'x'. Reorder the terms: 29 + 2 + -12x + -3x + 8x2 = -2 + 3x + 2 + -3x Combine like terms: 29 + 2 = 31 31 + -12x + -3x + 8x2 = -2 + 3x + 2 + -3x Combine like terms: -12x + -3x = -15x 31 + -15x + 8x2 = -2 + 3x + 2 + -3x Reorder the terms: 31 + -15x + 8x2 = -2 + 2 + 3x + -3x Combine like terms: -2 + 2 = 0 31 + -15x + 8x2 = 0 + 3x + -3x 31 + -15x + 8x2 = 3x + -3x Combine like terms: 3x + -3x = 0 31 + -15x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 3.875 + -1.875x + x2 = 0 Move the constant term to the right: Add '-3.875' to each side of the equation. 3.875 + -1.875x + -3.875 + x2 = 0 + -3.875 Reorder the terms: 3.875 + -3.875 + -1.875x + x2 = 0 + -3.875 Combine like terms: 3.875 + -3.875 = 0.000 0.000 + -1.875x + x2 = 0 + -3.875 -1.875x + x2 = 0 + -3.875 Combine like terms: 0 + -3.875 = -3.875 -1.875x + x2 = -3.875 The x term is -1.875x. Take half its coefficient (-0.9375). Square it (0.87890625) and add it to both sides. Add '0.87890625' to each side of the equation. -1.875x + 0.87890625 + x2 = -3.875 + 0.87890625 Reorder the terms: 0.87890625 + -1.875x + x2 = -3.875 + 0.87890625 Combine like terms: -3.875 + 0.87890625 = -2.99609375 0.87890625 + -1.875x + x2 = -2.99609375 Factor a perfect square on the left side: (x + -0.9375)(x + -0.9375) = -2.99609375 Can't calculate square root of the right side. The solution to this equation could not be determined.
