Simplifying x6 + -20x3 + 343 = 0 Reorder the terms: 343 + -20x3 + x6 = 0 Solving 343 + -20x3 + x6 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-343' to each side of the equation. 343 + -20x3 + -343 + x6 = 0 + -343 Reorder the terms: 343 + -343 + -20x3 + x6 = 0 + -343 Combine like terms: 343 + -343 = 0 0 + -20x3 + x6 = 0 + -343 -20x3 + x6 = 0 + -343 Combine like terms: 0 + -343 = -343 -20x3 + x6 = -343 The x term is -20x3. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20x3 + 100 + x6 = -343 + 100 Reorder the terms: 100 + -20x3 + x6 = -343 + 100 Combine like terms: -343 + 100 = -243 100 + -20x3 + x6 = -243 Factor a perfect square on the left side: (x3 + -10)(x3 + -10) = -243 Can't calculate square root of the right side. The solution to this equation could not be determined.
