Simplifying 0 = 5x2 + 40x + -4 Reorder the terms: 0 = -4 + 40x + 5x2 Solving 0 = -4 + 40x + 5x2 Solving for variable 'x'. Combine like terms: 0 + 4 = 4 4 + -40x + -5x2 = -4 + 40x + 5x2 + 4 + -40x + -5x2 Reorder the terms: 4 + -40x + -5x2 = -4 + 4 + 40x + -40x + 5x2 + -5x2 Combine like terms: -4 + 4 = 0 4 + -40x + -5x2 = 0 + 40x + -40x + 5x2 + -5x2 4 + -40x + -5x2 = 40x + -40x + 5x2 + -5x2 Combine like terms: 40x + -40x = 0 4 + -40x + -5x2 = 0 + 5x2 + -5x2 4 + -40x + -5x2 = 5x2 + -5x2 Combine like terms: 5x2 + -5x2 = 0 4 + -40x + -5x2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -0.8 + 8x + x2 = 0 Move the constant term to the right: Add '0.8' to each side of the equation. -0.8 + 8x + 0.8 + x2 = 0 + 0.8 Reorder the terms: -0.8 + 0.8 + 8x + x2 = 0 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + 8x + x2 = 0 + 0.8 8x + x2 = 0 + 0.8 Combine like terms: 0 + 0.8 = 0.8 8x + x2 = 0.8 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 = 0.8 + 16 Reorder the terms: 16 + 8x + x2 = 0.8 + 16 Combine like terms: 0.8 + 16 = 16.8 16 + 8x + x2 = 16.8 Factor a perfect square on the left side: (x + 4)(x + 4) = 16.8 Calculate the square root of the right side: 4.098780306 Break this problem into two subproblems by setting (x + 4) equal to 4.098780306 and -4.098780306.Subproblem 1
x + 4 = 4.098780306 Simplifying x + 4 = 4.098780306 Reorder the terms: 4 + x = 4.098780306 Solving 4 + x = 4.098780306 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 = 4.098780306 + -4 Combine like terms: 4 + -4 = 0 0 + x = 4.098780306 + -4 x = 4.098780306 + -4 Combine like terms: 4.098780306 + -4 = 0.098780306 x = 0.098780306 Simplifying x = 0.098780306Subproblem 2
x + 4 = -4.098780306 Simplifying x + 4 = -4.098780306 Reorder the terms: 4 + x = -4.098780306 Solving 4 + x = -4.098780306 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 = -4.098780306 + -4 Combine like terms: 4 + -4 = 0 0 + x = -4.098780306 + -4 x = -4.098780306 + -4 Combine like terms: -4.098780306 + -4 = -8.098780306 x = -8.098780306 Simplifying x = -8.098780306Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.098780306, -8.098780306}
