Simplifying 0 = x2 + 2x + -30 Reorder the terms: 0 = -30 + 2x + x2 Solving 0 = -30 + 2x + x2 Solving for variable 'x'. Combine like terms: 0 + 30 = 30 30 + -2x + -1x2 = -30 + 2x + x2 + 30 + -2x + -1x2 Reorder the terms: 30 + -2x + -1x2 = -30 + 30 + 2x + -2x + x2 + -1x2 Combine like terms: -30 + 30 = 0 30 + -2x + -1x2 = 0 + 2x + -2x + x2 + -1x2 30 + -2x + -1x2 = 2x + -2x + x2 + -1x2 Combine like terms: 2x + -2x = 0 30 + -2x + -1x2 = 0 + x2 + -1x2 30 + -2x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 30 + -2x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -30 + 2x + x2 = 0 Move the constant term to the right: Add '30' to each side of the equation. -30 + 2x + 30 + x2 = 0 + 30 Reorder the terms: -30 + 30 + 2x + x2 = 0 + 30 Combine like terms: -30 + 30 = 0 0 + 2x + x2 = 0 + 30 2x + x2 = 0 + 30 Combine like terms: 0 + 30 = 30 2x + x2 = 30 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 = 30 + 1 Reorder the terms: 1 + 2x + x2 = 30 + 1 Combine like terms: 30 + 1 = 31 1 + 2x + x2 = 31 Factor a perfect square on the left side: (x + 1)(x + 1) = 31 Calculate the square root of the right side: 5.567764363 Break this problem into two subproblems by setting (x + 1) equal to 5.567764363 and -5.567764363.Subproblem 1
x + 1 = 5.567764363 Simplifying x + 1 = 5.567764363 Reorder the terms: 1 + x = 5.567764363 Solving 1 + x = 5.567764363 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 = 5.567764363 + -1 Combine like terms: 1 + -1 = 0 0 + x = 5.567764363 + -1 x = 5.567764363 + -1 Combine like terms: 5.567764363 + -1 = 4.567764363 x = 4.567764363 Simplifying x = 4.567764363Subproblem 2
x + 1 = -5.567764363 Simplifying x + 1 = -5.567764363 Reorder the terms: 1 + x = -5.567764363 Solving 1 + x = -5.567764363 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 = -5.567764363 + -1 Combine like terms: 1 + -1 = 0 0 + x = -5.567764363 + -1 x = -5.567764363 + -1 Combine like terms: -5.567764363 + -1 = -6.567764363 x = -6.567764363 Simplifying x = -6.567764363Solution
