Simplifying 2x2 + 14x2 + 3x + 21 = 0 Reorder the terms: 21 + 3x + 2x2 + 14x2 = 0 Combine like terms: 2x2 + 14x2 = 16x2 21 + 3x + 16x2 = 0 Solving 21 + 3x + 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'. 1.3125 + 0.1875x + x2 = 0 Move the constant term to the right: Add '-1.3125' to each side of the equation. 1.3125 + 0.1875x + -1.3125 + x2 = 0 + -1.3125 Reorder the terms: 1.3125 + -1.3125 + 0.1875x + x2 = 0 + -1.3125 Combine like terms: 1.3125 + -1.3125 = 0.0000 0.0000 + 0.1875x + x2 = 0 + -1.3125 0.1875x + x2 = 0 + -1.3125 Combine like terms: 0 + -1.3125 = -1.3125 0.1875x + x2 = -1.3125 The x term is 0.1875x. Take half its coefficient (0.09375). Square it (0.0087890625) and add it to both sides. Add '0.0087890625' to each side of the equation. 0.1875x + 0.0087890625 + x2 = -1.3125 + 0.0087890625 Reorder the terms: 0.0087890625 + 0.1875x + x2 = -1.3125 + 0.0087890625 Combine like terms: -1.3125 + 0.0087890625 = -1.3037109375 0.0087890625 + 0.1875x + x2 = -1.3037109375 Factor a perfect square on the left side: (x + 0.09375)(x + 0.09375) = -1.3037109375 Can't calculate square root of the right side. The solution to this equation could not be determined.
