Simplifying s2 + 16s = -45 Reorder the terms: 16s + s2 = -45 Solving 16s + s2 = -45 Solving for variable 's'. Reorder the terms: 45 + 16s + s2 = -45 + 45 Combine like terms: -45 + 45 = 0 45 + 16s + s2 = 0 Begin completing the square. Move the constant term to the right: Add '-45' to each side of the equation. 45 + 16s + -45 + s2 = 0 + -45 Reorder the terms: 45 + -45 + 16s + s2 = 0 + -45 Combine like terms: 45 + -45 = 0 0 + 16s + s2 = 0 + -45 16s + s2 = 0 + -45 Combine like terms: 0 + -45 = -45 16s + s2 = -45 The s term is 16s. Take half its coefficient (8). Square it (64) and add it to both sides. Add '64' to each side of the equation. 16s + 64 + s2 = -45 + 64 Reorder the terms: 64 + 16s + s2 = -45 + 64 Combine like terms: -45 + 64 = 19 64 + 16s + s2 = 19 Factor a perfect square on the left side: (s + 8)(s + 8) = 19 Calculate the square root of the right side: 4.358898944 Break this problem into two subproblems by setting (s + 8) equal to 4.358898944 and -4.358898944.Subproblem 1
s + 8 = 4.358898944 Simplifying s + 8 = 4.358898944 Reorder the terms: 8 + s = 4.358898944 Solving 8 + s = 4.358898944 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + s = 4.358898944 + -8 Combine like terms: 8 + -8 = 0 0 + s = 4.358898944 + -8 s = 4.358898944 + -8 Combine like terms: 4.358898944 + -8 = -3.641101056 s = -3.641101056 Simplifying s = -3.641101056Subproblem 2
