Simplifying 149 = x2 + 4x + 3 Reorder the terms: 149 = 3 + 4x + x2 Solving 149 = 3 + 4x + x2 Solving for variable 'x'. Combine like terms: 149 + -3 = 146 146 + -4x + -1x2 = 3 + 4x + x2 + -3 + -4x + -1x2 Reorder the terms: 146 + -4x + -1x2 = 3 + -3 + 4x + -4x + x2 + -1x2 Combine like terms: 3 + -3 = 0 146 + -4x + -1x2 = 0 + 4x + -4x + x2 + -1x2 146 + -4x + -1x2 = 4x + -4x + x2 + -1x2 Combine like terms: 4x + -4x = 0 146 + -4x + -1x2 = 0 + x2 + -1x2 146 + -4x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 146 + -4x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -146 + 4x + x2 = 0 Move the constant term to the right: Add '146' to each side of the equation. -146 + 4x + 146 + x2 = 0 + 146 Reorder the terms: -146 + 146 + 4x + x2 = 0 + 146 Combine like terms: -146 + 146 = 0 0 + 4x + x2 = 0 + 146 4x + x2 = 0 + 146 Combine like terms: 0 + 146 = 146 4x + x2 = 146 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = 146 + 4 Reorder the terms: 4 + 4x + x2 = 146 + 4 Combine like terms: 146 + 4 = 150 4 + 4x + x2 = 150 Factor a perfect square on the left side: (x + 2)(x + 2) = 150 Calculate the square root of the right side: 12.247448714 Break this problem into two subproblems by setting (x + 2) equal to 12.247448714 and -12.247448714.Subproblem 1
x + 2 = 12.247448714 Simplifying x + 2 = 12.247448714 Reorder the terms: 2 + x = 12.247448714 Solving 2 + x = 12.247448714 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 12.247448714 + -2 Combine like terms: 2 + -2 = 0 0 + x = 12.247448714 + -2 x = 12.247448714 + -2 Combine like terms: 12.247448714 + -2 = 10.247448714 x = 10.247448714 Simplifying x = 10.247448714Subproblem 2
x + 2 = -12.247448714 Simplifying x + 2 = -12.247448714 Reorder the terms: 2 + x = -12.247448714 Solving 2 + x = -12.247448714 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -12.247448714 + -2 Combine like terms: 2 + -2 = 0 0 + x = -12.247448714 + -2 x = -12.247448714 + -2 Combine like terms: -12.247448714 + -2 = -14.247448714 x = -14.247448714 Simplifying x = -14.247448714Solution
The solution to the problem is based on the solutions from the subproblems. x = {10.247448714, -14.247448714}
