Simplifying -5x2 + -12x + 4 = 0 Reorder the terms: 4 + -12x + -5x2 = 0 Solving 4 + -12x + -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'. -0.8 + 2.4x + x2 = 0 Move the constant term to the right: Add '0.8' to each side of the equation. -0.8 + 2.4x + 0.8 + x2 = 0 + 0.8 Reorder the terms: -0.8 + 0.8 + 2.4x + x2 = 0 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + 2.4x + x2 = 0 + 0.8 2.4x + x2 = 0 + 0.8 Combine like terms: 0 + 0.8 = 0.8 2.4x + x2 = 0.8 The x term is 2.4x. Take half its coefficient (1.2). Square it (1.44) and add it to both sides. Add '1.44' to each side of the equation. 2.4x + 1.44 + x2 = 0.8 + 1.44 Reorder the terms: 1.44 + 2.4x + x2 = 0.8 + 1.44 Combine like terms: 0.8 + 1.44 = 2.24 1.44 + 2.4x + x2 = 2.24 Factor a perfect square on the left side: (x + 1.2)(x + 1.2) = 2.24 Calculate the square root of the right side: 1.496662955 Break this problem into two subproblems by setting (x + 1.2) equal to 1.496662955 and -1.496662955.Subproblem 1
x + 1.2 = 1.496662955 Simplifying x + 1.2 = 1.496662955 Reorder the terms: 1.2 + x = 1.496662955 Solving 1.2 + x = 1.496662955 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + x = 1.496662955 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + x = 1.496662955 + -1.2 x = 1.496662955 + -1.2 Combine like terms: 1.496662955 + -1.2 = 0.296662955 x = 0.296662955 Simplifying x = 0.296662955Subproblem 2
x + 1.2 = -1.496662955 Simplifying x + 1.2 = -1.496662955 Reorder the terms: 1.2 + x = -1.496662955 Solving 1.2 + x = -1.496662955 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + x = -1.496662955 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + x = -1.496662955 + -1.2 x = -1.496662955 + -1.2 Combine like terms: -1.496662955 + -1.2 = -2.696662955 x = -2.696662955 Simplifying x = -2.696662955Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.296662955, -2.696662955}
