Simplifying 3x4 + -7x2 + 12 = 0 Reorder the terms: 12 + -7x2 + 3x4 = 0 Solving 12 + -7x2 + 3x4 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 4 + -2.333333333x2 + x4 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + -2.333333333x2 + -4 + x4 = 0 + -4 Reorder the terms: 4 + -4 + -2.333333333x2 + x4 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -2.333333333x2 + x4 = 0 + -4 -2.333333333x2 + x4 = 0 + -4 Combine like terms: 0 + -4 = -4 -2.333333333x2 + x4 = -4 The x term is -2.333333333x2. Take half its coefficient (-1.166666667). Square it (1.361111112) and add it to both sides. Add '1.361111112' to each side of the equation. -2.333333333x2 + 1.361111112 + x4 = -4 + 1.361111112 Reorder the terms: 1.361111112 + -2.333333333x2 + x4 = -4 + 1.361111112 Combine like terms: -4 + 1.361111112 = -2.638888888 1.361111112 + -2.333333333x2 + x4 = -2.638888888 Factor a perfect square on the left side: (x2 + -1.166666667)(x2 + -1.166666667) = -2.638888888 Can't calculate square root of the right side. The solution to this equation could not be determined.
