Simplifying 0 = x2 + 10x + -4 Reorder the terms: 0 = -4 + 10x + x2 Solving 0 = -4 + 10x + x2 Solving for variable 'x'. Combine like terms: 0 + 4 = 4 4 + -10x + -1x2 = -4 + 10x + x2 + 4 + -10x + -1x2 Reorder the terms: 4 + -10x + -1x2 = -4 + 4 + 10x + -10x + x2 + -1x2 Combine like terms: -4 + 4 = 0 4 + -10x + -1x2 = 0 + 10x + -10x + x2 + -1x2 4 + -10x + -1x2 = 10x + -10x + x2 + -1x2 Combine like terms: 10x + -10x = 0 4 + -10x + -1x2 = 0 + x2 + -1x2 4 + -10x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 4 + -10x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -4 + 10x + x2 = 0 Move the constant term to the right: Add '4' to each side of the equation. -4 + 10x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + 10x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 10x + x2 = 0 + 4 10x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 10x + x2 = 4 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 = 4 + 25 Reorder the terms: 25 + 10x + x2 = 4 + 25 Combine like terms: 4 + 25 = 29 25 + 10x + x2 = 29 Factor a perfect square on the left side: (x + 5)(x + 5) = 29 Calculate the square root of the right side: 5.385164807 Break this problem into two subproblems by setting (x + 5) equal to 5.385164807 and -5.385164807.Subproblem 1
x + 5 = 5.385164807 Simplifying x + 5 = 5.385164807 Reorder the terms: 5 + x = 5.385164807 Solving 5 + x = 5.385164807 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 = 5.385164807 + -5 Combine like terms: 5 + -5 = 0 0 + x = 5.385164807 + -5 x = 5.385164807 + -5 Combine like terms: 5.385164807 + -5 = 0.385164807 x = 0.385164807 Simplifying x = 0.385164807Subproblem 2
x + 5 = -5.385164807 Simplifying x + 5 = -5.385164807 Reorder the terms: 5 + x = -5.385164807 Solving 5 + x = -5.385164807 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 = -5.385164807 + -5 Combine like terms: 5 + -5 = 0 0 + x = -5.385164807 + -5 x = -5.385164807 + -5 Combine like terms: -5.385164807 + -5 = -10.385164807 x = -10.385164807 Simplifying x = -10.385164807Solution
