Simplifying 5k2 + 4k + -3 = 0 Reorder the terms: -3 + 4k + 5k2 = 0 Solving -3 + 4k + 5k2 = 0 Solving for variable 'k'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -0.6 + 0.8k + k2 = 0 Move the constant term to the right: Add '0.6' to each side of the equation. -0.6 + 0.8k + 0.6 + k2 = 0 + 0.6 Reorder the terms: -0.6 + 0.6 + 0.8k + k2 = 0 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + 0.8k + k2 = 0 + 0.6 0.8k + k2 = 0 + 0.6 Combine like terms: 0 + 0.6 = 0.6 0.8k + k2 = 0.6 The k term is 0.8k. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8k + 0.16 + k2 = 0.6 + 0.16 Reorder the terms: 0.16 + 0.8k + k2 = 0.6 + 0.16 Combine like terms: 0.6 + 0.16 = 0.76 0.16 + 0.8k + k2 = 0.76 Factor a perfect square on the left side: (k + 0.4)(k + 0.4) = 0.76 Calculate the square root of the right side: 0.871779789 Break this problem into two subproblems by setting (k + 0.4) equal to 0.871779789 and -0.871779789.Subproblem 1
k + 0.4 = 0.871779789 Simplifying k + 0.4 = 0.871779789 Reorder the terms: 0.4 + k = 0.871779789 Solving 0.4 + k = 0.871779789 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + k = 0.871779789 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + k = 0.871779789 + -0.4 k = 0.871779789 + -0.4 Combine like terms: 0.871779789 + -0.4 = 0.471779789 k = 0.471779789 Simplifying k = 0.471779789Subproblem 2
k + 0.4 = -0.871779789 Simplifying k + 0.4 = -0.871779789 Reorder the terms: 0.4 + k = -0.871779789 Solving 0.4 + k = -0.871779789 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + k = -0.871779789 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + k = -0.871779789 + -0.4 k = -0.871779789 + -0.4 Combine like terms: -0.871779789 + -0.4 = -1.271779789 k = -1.271779789 Simplifying k = -1.271779789Solution
The solution to the problem is based on the solutions from the subproblems. k = {0.471779789, -1.271779789}
