Simplifying 7s = 2s2 + 4 Reorder the terms: 7s = 4 + 2s2 Solving 7s = 4 + 2s2 Solving for variable 's'. Reorder the terms: -4 + 7s + -2s2 = 4 + 2s2 + -4 + -2s2 Reorder the terms: -4 + 7s + -2s2 = 4 + -4 + 2s2 + -2s2 Combine like terms: 4 + -4 = 0 -4 + 7s + -2s2 = 0 + 2s2 + -2s2 -4 + 7s + -2s2 = 2s2 + -2s2 Combine like terms: 2s2 + -2s2 = 0 -4 + 7s + -2s2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 2 + -3.5s + s2 = 0 Move the constant term to the right: Add '-2' to each side of the equation. 2 + -3.5s + -2 + s2 = 0 + -2 Reorder the terms: 2 + -2 + -3.5s + s2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -3.5s + s2 = 0 + -2 -3.5s + s2 = 0 + -2 Combine like terms: 0 + -2 = -2 -3.5s + s2 = -2 The s term is -3.5s. Take half its coefficient (-1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. -3.5s + 3.0625 + s2 = -2 + 3.0625 Reorder the terms: 3.0625 + -3.5s + s2 = -2 + 3.0625 Combine like terms: -2 + 3.0625 = 1.0625 3.0625 + -3.5s + s2 = 1.0625 Factor a perfect square on the left side: (s + -1.75)(s + -1.75) = 1.0625 Calculate the square root of the right side: 1.030776406 Break this problem into two subproblems by setting (s + -1.75) equal to 1.030776406 and -1.030776406.Subproblem 1
s + -1.75 = 1.030776406 Simplifying s + -1.75 = 1.030776406 Reorder the terms: -1.75 + s = 1.030776406 Solving -1.75 + s = 1.030776406 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '1.75' to each side of the equation. -1.75 + 1.75 + s = 1.030776406 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + s = 1.030776406 + 1.75 s = 1.030776406 + 1.75 Combine like terms: 1.030776406 + 1.75 = 2.780776406 s = 2.780776406 Simplifying s = 2.780776406Subproblem 2
s + -1.75 = -1.030776406 Simplifying s + -1.75 = -1.030776406 Reorder the terms: -1.75 + s = -1.030776406 Solving -1.75 + s = -1.030776406 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '1.75' to each side of the equation. -1.75 + 1.75 + s = -1.030776406 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + s = -1.030776406 + 1.75 s = -1.030776406 + 1.75 Combine like terms: -1.030776406 + 1.75 = 0.719223594 s = 0.719223594 Simplifying s = 0.719223594Solution
The solution to the problem is based on the solutions from the subproblems. s = {2.780776406, 0.719223594}
