Simplifying 4x + 2x2 = 53 Solving 4x + 2x2 = 53 Solving for variable 'x'. Reorder the terms: -53 + 4x + 2x2 = 53 + -53 Combine like terms: 53 + -53 = 0 -53 + 4x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -26.5 + 2x + x2 = 0 Move the constant term to the right: Add '26.5' to each side of the equation. -26.5 + 2x + 26.5 + x2 = 0 + 26.5 Reorder the terms: -26.5 + 26.5 + 2x + x2 = 0 + 26.5 Combine like terms: -26.5 + 26.5 = 0.0 0.0 + 2x + x2 = 0 + 26.5 2x + x2 = 0 + 26.5 Combine like terms: 0 + 26.5 = 26.5 2x + x2 = 26.5 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 26.5 + 1 Reorder the terms: 1 + 2x + x2 = 26.5 + 1 Combine like terms: 26.5 + 1 = 27.5 1 + 2x + x2 = 27.5 Factor a perfect square on the left side: (x + 1)(x + 1) = 27.5 Calculate the square root of the right side: 5.244044241 Break this problem into two subproblems by setting (x + 1) equal to 5.244044241 and -5.244044241.Subproblem 1
x + 1 = 5.244044241 Simplifying x + 1 = 5.244044241 Reorder the terms: 1 + x = 5.244044241 Solving 1 + x = 5.244044241 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 5.244044241 + -1 Combine like terms: 1 + -1 = 0 0 + x = 5.244044241 + -1 x = 5.244044241 + -1 Combine like terms: 5.244044241 + -1 = 4.244044241 x = 4.244044241 Simplifying x = 4.244044241Subproblem 2
x + 1 = -5.244044241 Simplifying x + 1 = -5.244044241 Reorder the terms: 1 + x = -5.244044241 Solving 1 + x = -5.244044241 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -5.244044241 + -1 Combine like terms: 1 + -1 = 0 0 + x = -5.244044241 + -1 x = -5.244044241 + -1 Combine like terms: -5.244044241 + -1 = -6.244044241 x = -6.244044241 Simplifying x = -6.244044241Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.244044241, -6.244044241}
