Simplifying z2 + -21z + -96 = 0 Reorder the terms: -96 + -21z + z2 = 0 Solving -96 + -21z + z2 = 0 Solving for variable 'z'. Begin completing the square. Move the constant term to the right: Add '96' to each side of the equation. -96 + -21z + 96 + z2 = 0 + 96 Reorder the terms: -96 + 96 + -21z + z2 = 0 + 96 Combine like terms: -96 + 96 = 0 0 + -21z + z2 = 0 + 96 -21z + z2 = 0 + 96 Combine like terms: 0 + 96 = 96 -21z + z2 = 96 The z term is -21z. Take half its coefficient (-10.5). Square it (110.25) and add it to both sides. Add '110.25' to each side of the equation. -21z + 110.25 + z2 = 96 + 110.25 Reorder the terms: 110.25 + -21z + z2 = 96 + 110.25 Combine like terms: 96 + 110.25 = 206.25 110.25 + -21z + z2 = 206.25 Factor a perfect square on the left side: (z + -10.5)(z + -10.5) = 206.25 Calculate the square root of the right side: 14.361406616 Break this problem into two subproblems by setting (z + -10.5) equal to 14.361406616 and -14.361406616.Subproblem 1
z + -10.5 = 14.361406616 Simplifying z + -10.5 = 14.361406616 Reorder the terms: -10.5 + z = 14.361406616 Solving -10.5 + z = 14.361406616 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '10.5' to each side of the equation. -10.5 + 10.5 + z = 14.361406616 + 10.5 Combine like terms: -10.5 + 10.5 = 0.0 0.0 + z = 14.361406616 + 10.5 z = 14.361406616 + 10.5 Combine like terms: 14.361406616 + 10.5 = 24.861406616 z = 24.861406616 Simplifying z = 24.861406616Subproblem 2
z + -10.5 = -14.361406616 Simplifying z + -10.5 = -14.361406616 Reorder the terms: -10.5 + z = -14.361406616 Solving -10.5 + z = -14.361406616 Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '10.5' to each side of the equation. -10.5 + 10.5 + z = -14.361406616 + 10.5 Combine like terms: -10.5 + 10.5 = 0.0 0.0 + z = -14.361406616 + 10.5 z = -14.361406616 + 10.5 Combine like terms: -14.361406616 + 10.5 = -3.861406616 z = -3.861406616 Simplifying z = -3.861406616Solution
