Simplifying 15z2 + 9z + 30 = 0 Reorder the terms: 30 + 9z + 15z2 = 0 Solving 30 + 9z + 15z2 = 0 Solving for variable 'z'. Factor out the Greatest Common Factor (GCF), '3'. 3(10 + 3z + 5z2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(10 + 3z + 5z2)' equal to zero and attempt to solve: Simplifying 10 + 3z + 5z2 = 0 Solving 10 + 3z + 5z2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 2 + 0.6z + z2 = 0 Move the constant term to the right: Add '-2' to each side of the equation. 2 + 0.6z + -2 + z2 = 0 + -2 Reorder the terms: 2 + -2 + 0.6z + z2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 0.6z + z2 = 0 + -2 0.6z + z2 = 0 + -2 Combine like terms: 0 + -2 = -2 0.6z + z2 = -2 The z term is 0.6z. Take half its coefficient (0.3). Square it (0.09) and add it to both sides. Add '0.09' to each side of the equation. 0.6z + 0.09 + z2 = -2 + 0.09 Reorder the terms: 0.09 + 0.6z + z2 = -2 + 0.09 Combine like terms: -2 + 0.09 = -1.91 0.09 + 0.6z + z2 = -1.91 Factor a perfect square on the left side: (z + 0.3)(z + 0.3) = -1.91 Can't calculate square root of the right side.
