Simplifying 5x2 + 30x + 29 = 0 Reorder the terms: 29 + 30x + 5x2 = 0 Solving 29 + 30x + 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'. 5.8 + 6x + x2 = 0 Move the constant term to the right: Add '-5.8' to each side of the equation. 5.8 + 6x + -5.8 + x2 = 0 + -5.8 Reorder the terms: 5.8 + -5.8 + 6x + x2 = 0 + -5.8 Combine like terms: 5.8 + -5.8 = 0.0 0.0 + 6x + x2 = 0 + -5.8 6x + x2 = 0 + -5.8 Combine like terms: 0 + -5.8 = -5.8 6x + x2 = -5.8 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = -5.8 + 9 Reorder the terms: 9 + 6x + x2 = -5.8 + 9 Combine like terms: -5.8 + 9 = 3.2 9 + 6x + x2 = 3.2 Factor a perfect square on the left side: (x + 3)(x + 3) = 3.2 Calculate the square root of the right side: 1.788854382 Break this problem into two subproblems by setting (x + 3) equal to 1.788854382 and -1.788854382.Subproblem 1
x + 3 = 1.788854382 Simplifying x + 3 = 1.788854382 Reorder the terms: 3 + x = 1.788854382 Solving 3 + x = 1.788854382 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 1.788854382 + -3 Combine like terms: 3 + -3 = 0 0 + x = 1.788854382 + -3 x = 1.788854382 + -3 Combine like terms: 1.788854382 + -3 = -1.211145618 x = -1.211145618 Simplifying x = -1.211145618Subproblem 2
x + 3 = -1.788854382 Simplifying x + 3 = -1.788854382 Reorder the terms: 3 + x = -1.788854382 Solving 3 + x = -1.788854382 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = -1.788854382 + -3 Combine like terms: 3 + -3 = 0 0 + x = -1.788854382 + -3 x = -1.788854382 + -3 Combine like terms: -1.788854382 + -3 = -4.788854382 x = -4.788854382 Simplifying x = -4.788854382Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.211145618, -4.788854382}
