Simplifying 2x4 + -3x2 + 50 = 0 Reorder the terms: 50 + -3x2 + 2x4 = 0 Solving 50 + -3x2 + 2x4 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 25 + -1.5x2 + x4 = 0 Move the constant term to the right: Add '-25' to each side of the equation. 25 + -1.5x2 + -25 + x4 = 0 + -25 Reorder the terms: 25 + -25 + -1.5x2 + x4 = 0 + -25 Combine like terms: 25 + -25 = 0 0 + -1.5x2 + x4 = 0 + -25 -1.5x2 + x4 = 0 + -25 Combine like terms: 0 + -25 = -25 -1.5x2 + x4 = -25 The x term is -1.5x2. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x2 + 0.5625 + x4 = -25 + 0.5625 Reorder the terms: 0.5625 + -1.5x2 + x4 = -25 + 0.5625 Combine like terms: -25 + 0.5625 = -24.4375 0.5625 + -1.5x2 + x4 = -24.4375 Factor a perfect square on the left side: (x2 + -0.75)(x2 + -0.75) = -24.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
