Simplifying (0.3c + 0.4)(c + 0.6) = 0 Reorder the terms: (0.4 + 0.3c)(c + 0.6) = 0 Reorder the terms: (0.4 + 0.3c)(0.6 + c) = 0 Multiply (0.4 + 0.3c) * (0.6 + c) (0.4(0.6 + c) + 0.3c * (0.6 + c)) = 0 ((0.6 * 0.4 + c * 0.4) + 0.3c * (0.6 + c)) = 0 ((0.24 + 0.4c) + 0.3c * (0.6 + c)) = 0 (0.24 + 0.4c + (0.6 * 0.3c + c * 0.3c)) = 0 (0.24 + 0.4c + (0.18c + 0.3c2)) = 0 Combine like terms: 0.4c + 0.18c = 0.58c (0.24 + 0.58c + 0.3c2) = 0 Solving 0.24 + 0.58c + 0.3c2 = 0 Solving for variable 'c'. Begin completing the square. Divide all terms by 0.3 the coefficient of the squared term: Divide each side by '0.3'. 0.8 + 1.933333333c + c2 = 0 Move the constant term to the right: Add '-0.8' to each side of the equation. 0.8 + 1.933333333c + -0.8 + c2 = 0 + -0.8 Reorder the terms: 0.8 + -0.8 + 1.933333333c + c2 = 0 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + 1.933333333c + c2 = 0 + -0.8 1.933333333c + c2 = 0 + -0.8 Combine like terms: 0 + -0.8 = -0.8 1.933333333c + c2 = -0.8 The c term is 1.933333333c. Take half its coefficient (0.9666666665). Square it (0.9344444441) and add it to both sides. Add '0.9344444441' to each side of the equation. 1.933333333c + 0.9344444441 + c2 = -0.8 + 0.9344444441 Reorder the terms: 0.9344444441 + 1.933333333c + c2 = -0.8 + 0.9344444441 Combine like terms: -0.8 + 0.9344444441 = 0.1344444441 0.9344444441 + 1.933333333c + c2 = 0.1344444441 Factor a perfect square on the left side: (c + 0.9666666665)(c + 0.9666666665) = 0.1344444441 Calculate the square root of the right side: 0.366666666 Break this problem into two subproblems by setting (c + 0.9666666665) equal to 0.366666666 and -0.366666666.Subproblem 1
c + 0.9666666665 = 0.366666666 Simplifying c + 0.9666666665 = 0.366666666 Reorder the terms: 0.9666666665 + c = 0.366666666 Solving 0.9666666665 + c = 0.366666666 Solving for variable 'c'.
