Simplifying x2 + 10x + 21 = 1156 Reorder the terms: 21 + 10x + x2 = 1156 Solving 21 + 10x + x2 = 1156 Solving for variable 'x'. Reorder the terms: 21 + -1156 + 10x + x2 = 1156 + -1156 Combine like terms: 21 + -1156 = -1135 -1135 + 10x + x2 = 1156 + -1156 Combine like terms: 1156 + -1156 = 0 -1135 + 10x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '1135' to each side of the equation. -1135 + 10x + 1135 + x2 = 0 + 1135 Reorder the terms: -1135 + 1135 + 10x + x2 = 0 + 1135 Combine like terms: -1135 + 1135 = 0 0 + 10x + x2 = 0 + 1135 10x + x2 = 0 + 1135 Combine like terms: 0 + 1135 = 1135 10x + x2 = 1135 The x term is 10x. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10x + 25 + x2 = 1135 + 25 Reorder the terms: 25 + 10x + x2 = 1135 + 25 Combine like terms: 1135 + 25 = 1160 25 + 10x + x2 = 1160 Factor a perfect square on the left side: (x + 5)(x + 5) = 1160 Calculate the square root of the right side: 34.058772732 Break this problem into two subproblems by setting (x + 5) equal to 34.058772732 and -34.058772732.Subproblem 1
x + 5 = 34.058772732 Simplifying x + 5 = 34.058772732 Reorder the terms: 5 + x = 34.058772732 Solving 5 + x = 34.058772732 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = 34.058772732 + -5 Combine like terms: 5 + -5 = 0 0 + x = 34.058772732 + -5 x = 34.058772732 + -5 Combine like terms: 34.058772732 + -5 = 29.058772732 x = 29.058772732 Simplifying x = 29.058772732Subproblem 2
x + 5 = -34.058772732 Simplifying x + 5 = -34.058772732 Reorder the terms: 5 + x = -34.058772732 Solving 5 + x = -34.058772732 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = -34.058772732 + -5 Combine like terms: 5 + -5 = 0 0 + x = -34.058772732 + -5 x = -34.058772732 + -5 Combine like terms: -34.058772732 + -5 = -39.058772732 x = -39.058772732 Simplifying x = -39.058772732Solution
The solution to the problem is based on the solutions from the subproblems. x = {29.058772732, -39.058772732}
