Simplifying 2x4 = 7x2 + -15 Reorder the terms: 2x4 = -15 + 7x2 Solving 2x4 = -15 + 7x2 Solving for variable 'x'. Reorder the terms: 15 + -7x2 + 2x4 = -15 + 7x2 + 15 + -7x2 Reorder the terms: 15 + -7x2 + 2x4 = -15 + 15 + 7x2 + -7x2 Combine like terms: -15 + 15 = 0 15 + -7x2 + 2x4 = 0 + 7x2 + -7x2 15 + -7x2 + 2x4 = 7x2 + -7x2 Combine like terms: 7x2 + -7x2 = 0 15 + -7x2 + 2x4 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 7.5 + -3.5x2 + x4 = 0 Move the constant term to the right: Add '-7.5' to each side of the equation. 7.5 + -3.5x2 + -7.5 + x4 = 0 + -7.5 Reorder the terms: 7.5 + -7.5 + -3.5x2 + x4 = 0 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + -3.5x2 + x4 = 0 + -7.5 -3.5x2 + x4 = 0 + -7.5 Combine like terms: 0 + -7.5 = -7.5 -3.5x2 + x4 = -7.5 The x term is -3.5x2. Take half its coefficient (-1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. -3.5x2 + 3.0625 + x4 = -7.5 + 3.0625 Reorder the terms: 3.0625 + -3.5x2 + x4 = -7.5 + 3.0625 Combine like terms: -7.5 + 3.0625 = -4.4375 3.0625 + -3.5x2 + x4 = -4.4375 Factor a perfect square on the left side: (x2 + -1.75)(x2 + -1.75) = -4.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
