Simplifying 4x2 + 8x = 91 Reorder the terms: 8x + 4x2 = 91 Solving 8x + 4x2 = 91 Solving for variable 'x'. Reorder the terms: -91 + 8x + 4x2 = 91 + -91 Combine like terms: 91 + -91 = 0 -91 + 8x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -22.75 + 2x + x2 = 0 Move the constant term to the right: Add '22.75' to each side of the equation. -22.75 + 2x + 22.75 + x2 = 0 + 22.75 Reorder the terms: -22.75 + 22.75 + 2x + x2 = 0 + 22.75 Combine like terms: -22.75 + 22.75 = 0.00 0.00 + 2x + x2 = 0 + 22.75 2x + x2 = 0 + 22.75 Combine like terms: 0 + 22.75 = 22.75 2x + x2 = 22.75 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 = 22.75 + 1 Reorder the terms: 1 + 2x + x2 = 22.75 + 1 Combine like terms: 22.75 + 1 = 23.75 1 + 2x + x2 = 23.75 Factor a perfect square on the left side: (x + 1)(x + 1) = 23.75 Calculate the square root of the right side: 4.873397172 Break this problem into two subproblems by setting (x + 1) equal to 4.873397172 and -4.873397172.Subproblem 1
x + 1 = 4.873397172 Simplifying x + 1 = 4.873397172 Reorder the terms: 1 + x = 4.873397172 Solving 1 + x = 4.873397172 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 = 4.873397172 + -1 Combine like terms: 1 + -1 = 0 0 + x = 4.873397172 + -1 x = 4.873397172 + -1 Combine like terms: 4.873397172 + -1 = 3.873397172 x = 3.873397172 Simplifying x = 3.873397172Subproblem 2
x + 1 = -4.873397172 Simplifying x + 1 = -4.873397172 Reorder the terms: 1 + x = -4.873397172 Solving 1 + x = -4.873397172 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 = -4.873397172 + -1 Combine like terms: 1 + -1 = 0 0 + x = -4.873397172 + -1 x = -4.873397172 + -1 Combine like terms: -4.873397172 + -1 = -5.873397172 x = -5.873397172 Simplifying x = -5.873397172Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.873397172, -5.873397172}
