Simplifying z4 + -11z2 + 49 = 0 Reorder the terms: 49 + -11z2 + z4 = 0 Solving 49 + -11z2 + z4 = 0 Solving for variable 'z'. Begin completing the square. Move the constant term to the right: Add '-49' to each side of the equation. 49 + -11z2 + -49 + z4 = 0 + -49 Reorder the terms: 49 + -49 + -11z2 + z4 = 0 + -49 Combine like terms: 49 + -49 = 0 0 + -11z2 + z4 = 0 + -49 -11z2 + z4 = 0 + -49 Combine like terms: 0 + -49 = -49 -11z2 + z4 = -49 The z term is -11z2. Take half its coefficient (-5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. -11z2 + 30.25 + z4 = -49 + 30.25 Reorder the terms: 30.25 + -11z2 + z4 = -49 + 30.25 Combine like terms: -49 + 30.25 = -18.75 30.25 + -11z2 + z4 = -18.75 Factor a perfect square on the left side: (z2 + -5.5)(z2 + -5.5) = -18.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
