Simplifying 5x2 + 40x + 79 = 0 Reorder the terms: 79 + 40x + 5x2 = 0 Solving 79 + 40x + 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'. 15.8 + 8x + x2 = 0 Move the constant term to the right: Add '-15.8' to each side of the equation. 15.8 + 8x + -15.8 + x2 = 0 + -15.8 Reorder the terms: 15.8 + -15.8 + 8x + x2 = 0 + -15.8 Combine like terms: 15.8 + -15.8 = 0.0 0.0 + 8x + x2 = 0 + -15.8 8x + x2 = 0 + -15.8 Combine like terms: 0 + -15.8 = -15.8 8x + x2 = -15.8 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = -15.8 + 16 Reorder the terms: 16 + 8x + x2 = -15.8 + 16 Combine like terms: -15.8 + 16 = 0.2 16 + 8x + x2 = 0.2 Factor a perfect square on the left side: (x + 4)(x + 4) = 0.2 Calculate the square root of the right side: 0.447213596 Break this problem into two subproblems by setting (x + 4) equal to 0.447213596 and -0.447213596.Subproblem 1
x + 4 = 0.447213596 Simplifying x + 4 = 0.447213596 Reorder the terms: 4 + x = 0.447213596 Solving 4 + x = 0.447213596 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 0.447213596 + -4 Combine like terms: 4 + -4 = 0 0 + x = 0.447213596 + -4 x = 0.447213596 + -4 Combine like terms: 0.447213596 + -4 = -3.552786404 x = -3.552786404 Simplifying x = -3.552786404Subproblem 2
x + 4 = -0.447213596 Simplifying x + 4 = -0.447213596 Reorder the terms: 4 + x = -0.447213596 Solving 4 + x = -0.447213596 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = -0.447213596 + -4 Combine like terms: 4 + -4 = 0 0 + x = -0.447213596 + -4 x = -0.447213596 + -4 Combine like terms: -0.447213596 + -4 = -4.447213596 x = -4.447213596 Simplifying x = -4.447213596Solution
The solution to the problem is based on the solutions from the subproblems. x = {-3.552786404, -4.447213596}
