Simplifying 8x2 = 8x + -3 Reorder the terms: 8x2 = -3 + 8x Solving 8x2 = -3 + 8x Solving for variable 'x'. Reorder the terms: 3 + -8x + 8x2 = -3 + 8x + 3 + -8x Reorder the terms: 3 + -8x + 8x2 = -3 + 3 + 8x + -8x Combine like terms: -3 + 3 = 0 3 + -8x + 8x2 = 0 + 8x + -8x 3 + -8x + 8x2 = 8x + -8x Combine like terms: 8x + -8x = 0 3 + -8x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.375 + -1x + x2 = 0 Move the constant term to the right: Add '-0.375' to each side of the equation. 0.375 + -1x + -0.375 + x2 = 0 + -0.375 Reorder the terms: 0.375 + -0.375 + -1x + x2 = 0 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + -1x + x2 = 0 + -0.375 -1x + x2 = 0 + -0.375 Combine like terms: 0 + -0.375 = -0.375 -1x + x2 = -0.375 The x term is -1x. 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. -1x + 0.25 + x2 = -0.375 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -0.375 + 0.25 Combine like terms: -0.375 + 0.25 = -0.125 0.25 + -1x + x2 = -0.125 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = -0.125 Can't calculate square root of the right side. The solution to this equation could not be determined.
