Simplifying 5x2 + 77x + -6 = 0 Reorder the terms: -6 + 77x + 5x2 = 0 Solving -6 + 77x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1.2 + 15.4x + x2 = 0 Move the constant term to the right: Add '1.2' to each side of the equation. -1.2 + 15.4x + 1.2 + x2 = 0 + 1.2 Reorder the terms: -1.2 + 1.2 + 15.4x + x2 = 0 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + 15.4x + x2 = 0 + 1.2 15.4x + x2 = 0 + 1.2 Combine like terms: 0 + 1.2 = 1.2 15.4x + x2 = 1.2 The x term is 15.4x. Take half its coefficient (7.7). Square it (59.29) and add it to both sides. Add '59.29' to each side of the equation. 15.4x + 59.29 + x2 = 1.2 + 59.29 Reorder the terms: 59.29 + 15.4x + x2 = 1.2 + 59.29 Combine like terms: 1.2 + 59.29 = 60.49 59.29 + 15.4x + x2 = 60.49 Factor a perfect square on the left side: (x + 7.7)(x + 7.7) = 60.49 Calculate the square root of the right side: 7.777531742 Break this problem into two subproblems by setting (x + 7.7) equal to 7.777531742 and -7.777531742.Subproblem 1
x + 7.7 = 7.777531742 Simplifying x + 7.7 = 7.777531742 Reorder the terms: 7.7 + x = 7.777531742 Solving 7.7 + x = 7.777531742 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.7' to each side of the equation. 7.7 + -7.7 + x = 7.777531742 + -7.7 Combine like terms: 7.7 + -7.7 = 0.0 0.0 + x = 7.777531742 + -7.7 x = 7.777531742 + -7.7 Combine like terms: 7.777531742 + -7.7 = 0.077531742 x = 0.077531742 Simplifying x = 0.077531742Subproblem 2
x + 7.7 = -7.777531742 Simplifying x + 7.7 = -7.777531742 Reorder the terms: 7.7 + x = -7.777531742 Solving 7.7 + x = -7.777531742 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.7' to each side of the equation. 7.7 + -7.7 + x = -7.777531742 + -7.7 Combine like terms: 7.7 + -7.7 = 0.0 0.0 + x = -7.777531742 + -7.7 x = -7.777531742 + -7.7 Combine like terms: -7.777531742 + -7.7 = -15.477531742 x = -15.477531742 Simplifying x = -15.477531742Solution
