Simplifying 8x2 + -17x + 21 = 0 Reorder the terms: 21 + -17x + 8x2 = 0 Solving 21 + -17x + 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'. 2.625 + -2.125x + x2 = 0 Move the constant term to the right: Add '-2.625' to each side of the equation. 2.625 + -2.125x + -2.625 + x2 = 0 + -2.625 Reorder the terms: 2.625 + -2.625 + -2.125x + x2 = 0 + -2.625 Combine like terms: 2.625 + -2.625 = 0.000 0.000 + -2.125x + x2 = 0 + -2.625 -2.125x + x2 = 0 + -2.625 Combine like terms: 0 + -2.625 = -2.625 -2.125x + x2 = -2.625 The x term is -2.125x. Take half its coefficient (-1.0625). Square it (1.12890625) and add it to both sides. Add '1.12890625' to each side of the equation. -2.125x + 1.12890625 + x2 = -2.625 + 1.12890625 Reorder the terms: 1.12890625 + -2.125x + x2 = -2.625 + 1.12890625 Combine like terms: -2.625 + 1.12890625 = -1.49609375 1.12890625 + -2.125x + x2 = -1.49609375 Factor a perfect square on the left side: (x + -1.0625)(x + -1.0625) = -1.49609375 Can't calculate square root of the right side. The solution to this equation could not be determined.
