Simplifying 16x2 + -27x + 13 = 0 Reorder the terms: 13 + -27x + 16x2 = 0 Solving 13 + -27x + 16x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. 0.8125 + -1.6875x + x2 = 0 Move the constant term to the right: Add '-0.8125' to each side of the equation. 0.8125 + -1.6875x + -0.8125 + x2 = 0 + -0.8125 Reorder the terms: 0.8125 + -0.8125 + -1.6875x + x2 = 0 + -0.8125 Combine like terms: 0.8125 + -0.8125 = 0.0000 0.0000 + -1.6875x + x2 = 0 + -0.8125 -1.6875x + x2 = 0 + -0.8125 Combine like terms: 0 + -0.8125 = -0.8125 -1.6875x + x2 = -0.8125 The x term is -1.6875x. Take half its coefficient (-0.84375). Square it (0.7119140625) and add it to both sides. Add '0.7119140625' to each side of the equation. -1.6875x + 0.7119140625 + x2 = -0.8125 + 0.7119140625 Reorder the terms: 0.7119140625 + -1.6875x + x2 = -0.8125 + 0.7119140625 Combine like terms: -0.8125 + 0.7119140625 = -0.1005859375 0.7119140625 + -1.6875x + x2 = -0.1005859375 Factor a perfect square on the left side: (x + -0.84375)(x + -0.84375) = -0.1005859375 Can't calculate square root of the right side. The solution to this equation could not be determined.
