Simplifying x = 2x2 + 8 Reorder the terms: x = 8 + 2x2 Solving x = 8 + 2x2 Solving for variable 'x'. Reorder the terms: -8 + x + -2x2 = 8 + 2x2 + -8 + -2x2 Reorder the terms: -8 + x + -2x2 = 8 + -8 + 2x2 + -2x2 Combine like terms: 8 + -8 = 0 -8 + x + -2x2 = 0 + 2x2 + -2x2 -8 + x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 -8 + x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 4 + -0.5x + x2 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + -0.5x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + -0.5x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -0.5x + x2 = 0 + -4 -0.5x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 -0.5x + x2 = -4 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -0.5x + 0.25 + x2 = -4 + 0.25 Reorder the terms: 0.25 + -0.5x + x2 = -4 + 0.25 Combine like terms: -4 + 0.25 = -3.75 0.25 + -0.5x + x2 = -3.75 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -3.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
