Simplifying k2 + 35k + -9 = 0 Reorder the terms: -9 + 35k + k2 = 0 Solving -9 + 35k + k2 = 0 Solving for variable 'k'. Begin completing the square. Move the constant term to the right: Add '9' to each side of the equation. -9 + 35k + 9 + k2 = 0 + 9 Reorder the terms: -9 + 9 + 35k + k2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + 35k + k2 = 0 + 9 35k + k2 = 0 + 9 Combine like terms: 0 + 9 = 9 35k + k2 = 9 The k term is 35k. Take half its coefficient (17.5). Square it (306.25) and add it to both sides. Add '306.25' to each side of the equation. 35k + 306.25 + k2 = 9 + 306.25 Reorder the terms: 306.25 + 35k + k2 = 9 + 306.25 Combine like terms: 9 + 306.25 = 315.25 306.25 + 35k + k2 = 315.25 Factor a perfect square on the left side: (k + 17.5)(k + 17.5) = 315.25 Calculate the square root of the right side: 17.755280905 Break this problem into two subproblems by setting (k + 17.5) equal to 17.755280905 and -17.755280905.Subproblem 1
k + 17.5 = 17.755280905 Simplifying k + 17.5 = 17.755280905 Reorder the terms: 17.5 + k = 17.755280905 Solving 17.5 + k = 17.755280905 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-17.5' to each side of the equation. 17.5 + -17.5 + k = 17.755280905 + -17.5 Combine like terms: 17.5 + -17.5 = 0.0 0.0 + k = 17.755280905 + -17.5 k = 17.755280905 + -17.5 Combine like terms: 17.755280905 + -17.5 = 0.255280905 k = 0.255280905 Simplifying k = 0.255280905Subproblem 2
k + 17.5 = -17.755280905 Simplifying k + 17.5 = -17.755280905 Reorder the terms: 17.5 + k = -17.755280905 Solving 17.5 + k = -17.755280905 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-17.5' to each side of the equation. 17.5 + -17.5 + k = -17.755280905 + -17.5 Combine like terms: 17.5 + -17.5 = 0.0 0.0 + k = -17.755280905 + -17.5 k = -17.755280905 + -17.5 Combine like terms: -17.755280905 + -17.5 = -35.255280905 k = -35.255280905 Simplifying k = -35.255280905Solution
