Simplifying 0.2x2 + 6x + 4 = 0 Reorder the terms: 4 + 6x + 0.2x2 = 0 Solving 4 + 6x + 0.2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.2 the coefficient of the squared term: Divide each side by '0.2'. 20 + 30x + x2 = 0 Move the constant term to the right: Add '-20' to each side of the equation. 20 + 30x + -20 + x2 = 0 + -20 Reorder the terms: 20 + -20 + 30x + x2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + 30x + x2 = 0 + -20 30x + x2 = 0 + -20 Combine like terms: 0 + -20 = -20 30x + x2 = -20 The x term is 30x. Take half its coefficient (15). Square it (225) and add it to both sides. Add '225' to each side of the equation. 30x + 225 + x2 = -20 + 225 Reorder the terms: 225 + 30x + x2 = -20 + 225 Combine like terms: -20 + 225 = 205 225 + 30x + x2 = 205 Factor a perfect square on the left side: (x + 15)(x + 15) = 205 Calculate the square root of the right side: 14.317821063 Break this problem into two subproblems by setting (x + 15) equal to 14.317821063 and -14.317821063.Subproblem 1
x + 15 = 14.317821063 Simplifying x + 15 = 14.317821063 Reorder the terms: 15 + x = 14.317821063 Solving 15 + x = 14.317821063 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + x = 14.317821063 + -15 Combine like terms: 15 + -15 = 0 0 + x = 14.317821063 + -15 x = 14.317821063 + -15 Combine like terms: 14.317821063 + -15 = -0.682178937 x = -0.682178937 Simplifying x = -0.682178937Subproblem 2
x + 15 = -14.317821063 Simplifying x + 15 = -14.317821063 Reorder the terms: 15 + x = -14.317821063 Solving 15 + x = -14.317821063 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15' to each side of the equation. 15 + -15 + x = -14.317821063 + -15 Combine like terms: 15 + -15 = 0 0 + x = -14.317821063 + -15 x = -14.317821063 + -15 Combine like terms: -14.317821063 + -15 = -29.317821063 x = -29.317821063 Simplifying x = -29.317821063Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.682178937, -29.317821063}
