Simplifying 4x2 + 8x + 5 = 100 Reorder the terms: 5 + 8x + 4x2 = 100 Solving 5 + 8x + 4x2 = 100 Solving for variable 'x'. Reorder the terms: 5 + -100 + 8x + 4x2 = 100 + -100 Combine like terms: 5 + -100 = -95 -95 + 8x + 4x2 = 100 + -100 Combine like terms: 100 + -100 = 0 -95 + 8x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -23.75 + 2x + x2 = 0 Move the constant term to the right: Add '23.75' to each side of the equation. -23.75 + 2x + 23.75 + x2 = 0 + 23.75 Reorder the terms: -23.75 + 23.75 + 2x + x2 = 0 + 23.75 Combine like terms: -23.75 + 23.75 = 0.00 0.00 + 2x + x2 = 0 + 23.75 2x + x2 = 0 + 23.75 Combine like terms: 0 + 23.75 = 23.75 2x + x2 = 23.75 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 = 23.75 + 1 Reorder the terms: 1 + 2x + x2 = 23.75 + 1 Combine like terms: 23.75 + 1 = 24.75 1 + 2x + x2 = 24.75 Factor a perfect square on the left side: (x + 1)(x + 1) = 24.75 Calculate the square root of the right side: 4.974937186 Break this problem into two subproblems by setting (x + 1) equal to 4.974937186 and -4.974937186.Subproblem 1
x + 1 = 4.974937186 Simplifying x + 1 = 4.974937186 Reorder the terms: 1 + x = 4.974937186 Solving 1 + x = 4.974937186 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 = 4.974937186 + -1 Combine like terms: 1 + -1 = 0 0 + x = 4.974937186 + -1 x = 4.974937186 + -1 Combine like terms: 4.974937186 + -1 = 3.974937186 x = 3.974937186 Simplifying x = 3.974937186Subproblem 2
x + 1 = -4.974937186 Simplifying x + 1 = -4.974937186 Reorder the terms: 1 + x = -4.974937186 Solving 1 + x = -4.974937186 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 = -4.974937186 + -1 Combine like terms: 1 + -1 = 0 0 + x = -4.974937186 + -1 x = -4.974937186 + -1 Combine like terms: -4.974937186 + -1 = -5.974937186 x = -5.974937186 Simplifying x = -5.974937186Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.974937186, -5.974937186}
